According to the present invention described in the above 2, since the take-up mechanism has a rotor for taking up the linear member and a spring for applying a torque in one direction to the rotor, the rotor generally moves along the direction according to the torque applied by the spring. When the rotor rotates in one direction, the linear member is wound up on the rotor as the rotor rotates in one direction. Therefore, in the state where the linear member is connected to the fixing member by the connecting member, the slack of the linear member can be eliminated and tension can be generated on the linear member. On the other hand, when the connection state of the fixing member and the connecting member is released, the linear member is quickly wound up on the rotor and stored in the winding mechanism.

Since the coil spring rotates, it is possible to prevent overloading of pulleys and the like and prevent damage to the device. In addition, the tension generated by the linear member may be set to a predetermined value.

According to the present invention described in the above-mentioned 6, since the above-mentioned pulley is provided with two, and the above-mentioned coil spring is provided corresponding to each pulley, one of the pulleys is on the front side or the rear side of the vehicle chair, and is used for winding the One of the above-mentioned linear members connected to the above-mentioned fixing member, and the other pulley is on the front side or the rear side of the vehicle seat, and is used to take up the other of the above-mentioned linear member connected to the above-mentioned fixing member through the above-mentioned connecting member. One, so adopting one winding mechanism can roll up the two linear parts that are connected to the fixing part through the connecting part in the front side or the rear side of the vehicle seat, so that the operability is improved. In addition, since the same magnitude of tension can be generated in the two linear members, the vehicle seat can be fixed with good balance.

According to the present invention described in the above 7, since the take-up mechanism has a spring that applies a torque in one direction to the above-mentioned rotating shaft, the rotating shaft generally rotates in one direction according to the torque applied by the spring, thereby being able to rotate The shaft rotates in one direction to wind up the linear member on the pulley. Therefore, in a state where the linear member is connected to the fixing member via the connecting member, the slack of the linear member can be eliminated and tension can be formed in the linear member. On the other hand, when the connection state between the fixing member and the connecting member is released, the linear member is quickly wound up on the pulley and accommodated in the winding mechanism.

According to the present invention described in the above 8, since there is a pulling mechanism that pulls the linear member in the winding direction, by operating the pulling mechanism to pull the linear member in the winding direction, the wire can be further strengthened.

Detailed ways

The implementation of the present invention will be described below according to the embodiments shown in the drawings.

[Example 1]

Fig. 1 is a diagram showing a state in which a vehicle seat 1 according to Embodiment 1 of the present invention is fixed on a floor. As shown in FIG. 1 , the vehicle seat 1 of this embodiment has a structure including a vehicle seat fixing device 2 including a linear member 21 and a take-up mechanism 22 .

As the linear member 21 constituting the seat fixing device 2, two belts 21a, 21b (hereinafter referred to as "front side belts") installed on the front side of the vehicle seat 1 are used, and two belts 21a, 21b are installed on the rear side of the vehicle seat 1 when in use. 2 belts 21c, 21d (hereinafter referred to as "rear side belt"). The front side belts 21a, 21b and the rear side belts 21c, 21d are respectively provided with connecting members 23 which can be attached to and detached from the fixture 3 attached to the floor. The fixing part 3 and the connecting part 23 can be connected and detached from each other, and their shapes and structures are not particularly limited. In this embodiment, rail members 3a, 3b having grooves are used as the fixing member 3, and hooks 23a to 23d detachable from the grooves of the rail members 3a, 3b are used as the connecting member 23.

As the winding mechanism 22, it is preferable that both the front side belts 21a, 21b and the rear side belts 21c, 21d can be wound up and accommodated, but it is also possible that only the front side belts 21a, 21b and the rear side belts 21c, 21c, Either side of 21d is coiled up and contained. In the present embodiment, the winding mechanism 22 adopts a structure capable of winding and storing both the front side tapes 21a, 21b and the rear side tapes 21c, 21d.

As shown in FIGS. 2 to 4 , the coiling mechanism 22 adopted in this embodiment has a structure including a rotor 221 , a spring 222 , a pulling mechanism 223 , a locking mechanism 224 and a releasing mechanism 225 .

The rotor 221 is a member that functions to wind up the linear member 21, and may have any shape. In this embodiment, two rotors 221 are provided corresponding to the front belts 21a, 21b and the rear belts 21c, 21d which function as the linear member 21, respectively.

On the rotor 221a corresponding to the front side belts 21a, 21b (hereinafter referred to as "the first rotor"), the ends of the front side belts 21a, 21b are installed, and the front side belts are rotated along one direction by the first rotor 221a. 21a and 21b are wound on the first rotor 221a. On the other hand, on the rotor 221b corresponding to the rear side belts 21c, 21d (hereinafter referred to as "the second rotor"), the ends of the rear side belts 21c, 21d are attached, and the second rotor 221b rotates along one direction to The rear tapes 21c and 21d are wound around the second rotor 221b.

The spring 222 acts to apply torque in one direction to the rotor 221 . In this embodiment, the spring 222 is a coil spring, and two springs 222 are provided so as to respectively act on the first rotor 221a and the second rotor 221b.

The pulling mechanism 223 plays a role of pulling the linear member 21 in the winding direction, and its structure is not limited, as long as the above functions can be realized. Therefore, as the pulling mechanism 223, a structure that directly or indirectly applies torque in one direction to the rotor 221 may be employed, or a structure that directly acts on the linear member 21 may be employed.

The pulling mechanism 223 used in this embodiment has a structure including an operating lever 223a and a one-way clutch 223b. The operating lever 223a is rod-shaped, and is coupled to the first rotor 221a via the one-way clutch 223b. The operating lever 223a is swingable, and by operating it, power to rotate the first rotor 221a is generated. The one-way clutch 223b is sandwiched between the operating lever 223a and the first rotor 221a, and functions to transmit power to the first rotor 221a only when the operating lever 223a is moved in one direction.

According to the pulling mechanism 223, when the operating lever 223a is moved in one direction, the one-way clutch 223b is driven and the power generated by the movement of the operating lever 223a is transmitted to the first rotor 221a, so that the first rotor 221a Rotate in one direction. Therefore, the front side tapes 21a, 21b serving as the linear member 21 are directed in the winding direction. On the other hand, when the operation lever 223a is operated in the reverse direction, the one-way clutch 223b idles, and the power generated by the movement of the operation lever 223a is not transmitted to the first rotor 221a. Therefore, the first rotor 221a does not rotate, and the front belts 21a and 21b are not pulled.

If such a pulling mechanism 223 is used, after the operation rod 223a is swung, that is, after the operation rod 223a is moved in one direction, the simple and easy-to-handle operation of making it move in the opposite direction can be strengthened. The tension generated by the front side belts 21a, 21b.

The locking mechanism 224 functions to prevent the linear member 21 from being pulled out. As the lock mechanism 224, even when the linear member 21 is drawn in the take-up direction, it is a structure capable of preventing it. However, if such a lock mechanism is adopted, it is necessary to provide a lock mechanism not only to any one of the front side belts 21a, 21b and the rear side belts 21c, 21d but also to both side belts. In other words, if such a locking mechanism is provided only on the front side belts 21a, 21b, since the rear side belts 21c, 21d are pulled out to cause slack due to a large horizontal load increase from the rear of the vehicle seat 1, The front side belts 21a, 21b are not wound up due to the action of the locking mechanism, so the vehicle seat 1 moves forward and the front side belts 21a, 21b become loose. In order to prevent the occurrence of this situation, it is only necessary to set a locking mechanism of the same structure on the rear side belts 21c, 21d, so that even when a large horizontal load is applied from the rear relative to the vehicle seat 1, the rear side can be locked. The side belts 21c and 21d are not pulled out, but in this case, the number of parts increases and the size of the device also increases. Therefore, as the locking mechanism 224, it is preferable to allow this to occur when the linear member 21 is guided in the winding direction, and to prevent this when the linear member 21 is guided to the opposite direction of the winding direction. The structure in which this situation occurs. Therefore, the number of parts can be reduced and the device can be miniaturized.

The locking mechanism 224 used in this embodiment only prevents the drawing of the linear member 21, and as shown in FIGS. The eccentric cam 224b is disposed on the guide 224a, and the spring 224c is configured to apply a torque in one direction to the eccentric cam 224b. The seat fixing device 2 adopted in this embodiment has a structure in which only the front side belts 21a, 21b used as the linear member 21 are provided with the locking mechanism 224, and the front side belts 21a, 21b are driven from the eccentric cam 224b and the guide 224a. Therefore, in the locked state, the eccentric cam 224b presses against the front belts 21a, 21b located on the guide 224a, and the contact force and the frictional force generated when the front belts 21a, 21b are drawn out can prevent the front belt from being pulled out. Extraction of straps 21a, 21b. On the other hand, in the locked state, when leading the front side belts 21a, 21b to the winding direction, the eccentric cam 224b is approximately semicircular in side view, and its curved surface faces the direction in which the front side belts 21a, 21b are pulled out, so it is eccentric. The frictional force generated between the cam 224b and the front belts 21a, 21b is small. In this way, the front side tapes 21a, 21b are wound around the first rotor 221a. Therefore, since the front side belts 21a, 21b are wound by the first rotor 221a, even if a large horizontal load is applied to the vehicle seat 1 from the rear to pull out the rear side belts 21c, 21d, even if the vehicle seat 1 moves forward Even when moving, the front side belts 21a, 21b do not loosen.

The release mechanism 225 is used to release the locked state locked by the lock mechanism 224, and its structure is not limited as long as the above-mentioned function can be realized. In other words, if the hand of the operating portion of the releasing mechanism is removed, and the locking mechanism 224 operates to become locked, then when the linear member 21 is pulled out from the take-up mechanism 22, it is necessary to have the operating portion of the releasing mechanism. The hand and the hand holding the linear member 21 usually require two hands to work at the same time. For this point, if the release mechanism 225 can maintain the release state, even if the hand of the operation portion of the release mechanism 225 is taken away, the release state is maintained and the lock state is not in the locked state. It can be operated with one hand when it is pulled out.

As shown in Figures 2 and 4, the release mechanism 225 used in this embodiment has a bolt 225a installed at a position opposite to the eccentric cam 224b, a bolt holding portion 225b having a threaded hole for connecting the bolt 225a, and a bolt holding portion 225b protruding from the bolt 225a. The structure of the operation part 225c of the head part of 225a can maintain the release state by the coupling action of the male thread formed on the bolt 225a and the female thread formed in the threaded hole of the bolt holding part 225b.

That is, the release mechanism 225 pushes up the eccentric cam 224b by moving the operation part 225c in one direction, turning the bolt 225a in one direction, and advancing the end of the bolt 225a in contact with the eccentric cam 224b. In this way, since the gap formed between the eccentric cam 224b and the guide 224a becomes large, the locked state locked by the lock mechanism 224 is released. Therefore, even if the hand operating the operation part 225c is removed later, the bolt 225a and the threaded hole of the bolt holding part 225b are engaged, and will not rotate in the opposite direction unless an external force is applied, so the released state can be maintained. On the other hand, when the operation part 225c is operated in the reverse direction, the bolt 225a rotates in the reverse direction, and the tip of the bolt 225a retreats, so that the eccentric cam 224b rotates downward. Thereby, the clearance gap formed between the eccentric cam 224b and the guide 224a becomes small, and it becomes a locked state.

As shown in FIG. 1 , the take-up mechanism 22 of the vehicle seat fixing device 2 configured as above is attached to the lower portion of the armrests 1 a, 1 b of the vehicle seat 1 . In this way, by installing the take-up mechanism 22 on the lower part of the armrests 1a and 1b of the vehicle seat 1, the action point of the linear member 21 is not located at the lower part of the vehicle seat 1 but at the lower part of the armrests 1a and 1b. The chair 1 produces the action of the wire-like part 21 in a higher position. Therefore, it is possible to generate a fixing force sufficient to resist a horizontal load and a vertical load (in particular, a load acting in a direction against gravity) applied to the vehicle seat 1 . On the other hand, the front tapes 21a, 21b and the rear tapes 21c, 21d used as the linear member 21 are wound up and stored in the first rotor 221a and the second rotor 221b, respectively, when not in use. Therefore, there is no need for a helper to carry the vehicle seat fixing device 2, and it is not necessary to prepare a place for fixing the vehicle seat 1 in advance.

The vehicle seat 1 of this embodiment is used as follows. That is, when the vehicle seat 1 is fixed on the floor, first, the rear side belts 21c, 21d accommodated in the take-up mechanism 22 are drawn out, and the hook bodies 23c, 23d arranged at the ends thereof are connected with the hooks 23c, 23d installed on the floor. The rail members 3a, 3b are connected. Then, the operation part 225c of the release mechanism 225 is operated in one direction, and the bolt 225a is rotated in one direction. Thus, the locked state of the lock mechanism 224 is released, and the front side tapes 21a, 21b housed in the take-up mechanism can be drawn out. Next, the front side belts 21a, 21b housed in the winding mechanism 22 are pulled out, and the hook bodies 23a, 23b provided at the front ends are connected to the rail members 3a, 3b provided on the floor. Finally, the operation part 225c of the release mechanism 225 is moved in the opposite direction, and the bolt 225a is rotated in the opposite direction. Thereby, the lock mechanism 224 operates and becomes a locked state, and the withdrawal of the front side belt 21a, 21b is prevented.

As described above, when the front belts 21a, 21b and the rear belts 21c, 21d are connected to the rail members 3a, 3b through the hooks 23a-23d, tension is generated in the front belts 21a, 21b and the rear belts 21c, 21d, respectively. That is, since the winding mechanism 22 adopted in this embodiment has the first rotor 221 that winds the linear member 21 by rotating in one direction, and the spring 222 that applies torque in one direction to the rotor 221, If the rear belts 21c, 21d and the front belts 21a, 21b are pulled out from the take-up mechanism 22, the spring 222 accumulates the force to rotate the first rotor 221a and the second rotor 221b in one direction. Then, once the hook bodies 23a-23d are connected to the guide rail members 3a, 3b, and the withdrawal of the rear side belts 21c, 21d and the front side belts 21a, 21b is completed, the force accumulated in the spring 222 is released, and the first rotor 221a and the first rotor 221a The second rotor 221b rotates in one direction, and guides the front tapes 21a, 21b and the rear tapes 21c, 21d in the take-up direction. Therefore, in the state where the front side belts 21a, 21b and the rear side belts 21c, 21d are connected to the guide rail members 3a, 3b through the hooks 23a-23d, by the action of the spring 222, the front side belts 21a, 21b and the rear side belts 21c, 21d do not slack. The front side belts 21a, 21b and the rear side belts 21c, 21d generate tension.

When the force for fixing the vehicle seat 1 is further increased, the operating lever 223a constituting the pulling mechanism 223 is swung. As a result, the first rotor 221a rotates in one direction to wind up the front belts 21a, 21b, so the tension generated by the front belts 21a, 21b and the rear belts 21c, 21d is further enhanced, thereby firmly fixing the vehicle. chair1.

According to the vehicle seat 1 of the present embodiment, the take-up mechanism 22 is installed at the lower part of the armrests 1a, 1b, and the operation lever 223a is located at the hand of the vehicle seat user, so the vehicle seat user can operate the operation lever 223a by himself. The same applies to the operation of the operation unit 225c of the release mechanism 225 and the extraction of the front belts 21a, 21b and the rear belts 21c, 21d. Therefore, the user of the vehicle seat 1 can perform fixing work by himself. In addition, even if a helper (including people other than companions for the purpose of providing help) is required to perform the work, since the work is easy, the work load of the helper is greatly reduced.

In addition, according to the vehicle seat 1 of the present embodiment, as a device on the floor side, it is only necessary to have the fixture 3 for connecting the linear members 21 via the connecting member 23 . Minimization of floor-side equipment is possible. Therefore, it is easy to assemble in a new floor, and even an existing floor can be retrofitted with simple operation and at low cost. In addition, when the seat fastening device 2 is not used, only the fastening element 3 is present on the floor, so that the seat fastening device 2 itself does not need to occupy a certain floor area. Therefore, the use environment of the vehicle seat 1 can be improved.

[Example 2]

Fig. 5 is a diagram showing a state in which the vehicle seat 1 according to the second embodiment of the present invention is fixed on the floor. As shown in FIG. 5 , the vehicle seat 1 of the present embodiment has the same structure as the vehicle seat 1 of the first embodiment, including the seat fixing device 2 including the linear member 21 and the take-up mechanism 22 .

As the linear member 21, when in use, two wire ropes 21e, 21f (hereinafter referred to as "front side wire ropes") installed on the front side of the vehicle seat 1, two wires 21g installed on the rear side of the vehicle seat 1, 21h (hereinafter referred to as "rear wire rope"). The connection member 23 which can attach and detach to the fixing tool 3 attached to the floor is provided in front side wire rope 21e, 21f and rear side wire rope 21g, 21h, respectively. In this embodiment, the hooks 3c, 3d are pre-attached to the rail members 3a, 3b used as the fixture 3 . In addition, the connecting member 23 provided on the front side wire ropes 21e, 21f has an engaging portion 23e engaged with the hooks 3c, 3d functioning as the fixing member 3, and a handle 23f provided with the engaging portion 23e at the end. . Among them, it is preferable that the handle 23f is retractable. The handle 23f is retractable, and when not in use, the connecting member 23 is made smaller by shortening the handle 23f so that it can be accommodated or carried. On the other hand, as the connection member 23 provided in the rear side wire rope 21g, 21h, the hook body 23g which can be attached and detached to the groove|channel of rail member 3a, 3b is employ|adopted.

As the winding mechanism 22, the structure which can wind up and store both the front side wire ropes 21e, 21f and the rear side wire ropes 21g, 21h is employ|adopted. In this embodiment, as shown in FIGS. 6 and 7 , the coiling mechanism 22 used has a pulley 226, a coil spring 227, a rotating shaft 228, a spring 222, a pulling mechanism 223, a locking mechanism 224 and a releasing mechanism 225. Structure.

The pulley 226 is used to wind up the linear member 21 . In this embodiment, two pulleys 226 are provided corresponding to the front wire ropes 21e and 21f and the rear wire ropes 21g and 21h functioning as the linear member 21, respectively. Among the front side wire ropes 21e, 21f, on the pulley 226a (hereinafter referred to as "the first pulley") corresponding to one front side wire rope 21e, the ends of the front side wire ropes 21e, 21f are installed, and pass through the first pulley 226a along the One of the front side wire ropes 21e is wound around the first pulley 226a by rotating in one direction. On the other hand, the end of the other front side wire rope 21f is attached to the pulley 226b (hereinafter referred to as "the second pulley") corresponding to the other front side wire rope 21f, and is rotated in one direction by the second pulley 226b. And the other front side wire rope 21f is wound up by the 2nd pulley 226b.

The coil spring 227 is installed on both sides of the pulley 226 and clamps the pulley 226. Under normal conditions, the power to rotate the rotating shaft 228 is transmitted to the pulley 226 to rotate the pulley 226. On the other hand, the clamping of the above-mentioned coil spring When the force reaches the limit, the power transmission to the above-mentioned pulley 226 is cut off. In this embodiment, the coil springs 227 are respectively provided corresponding to the first pulley 226a and the second pulley 226b.

The rotation shaft 228 supports the coil spring 227 . The first pulley 226 a , the second pulley 226 b , and the coil spring 227 rotate around the rotation shaft 228 .

The spring 222 acts to apply a directional torque to the rotating shaft 228 . In this embodiment, the spring 222 is a coil spring.

As in Embodiment 1, the pulling mechanism 223 has a structure having an operating lever 223a and a one-way clutch 223b. The operating lever 223a is coupled to the rotary shaft 228 via the one-way clutch 223b. The operation lever 223a is oscillating, and when operated, power to rotate the rotation shaft 228 is generated. The one-way clutch 223b is sandwiched between the operation lever 223a and the rotation shaft 228, and functions to transmit power to the rotation shaft 228 only when the operation lever 223a is moved in one direction.

According to the pulling mechanism 223, when the operating lever 223a is moved in one direction, the one-way clutch 223b is driven and the power generated due to the movement of the operating lever 223a is transmitted to the rotating shaft 228, so that the rotating shaft 228 and the coil spring 227 They rotate together in one direction, and the first and second pulleys 226a and 226b rotate accordingly. Therefore, the front side wire ropes 21e, 21f serving as the linear member 21 are guided in the winding direction. On the other hand, when the operation lever 223a is operated in the reverse direction, the one-way clutch 223b idles, and the power generated by the movement of the operation lever 223a is not transmitted to the rotation shaft 228 . Therefore, the rotating shaft 228 does not rotate, and the front side wire ropes 21e, 21f are not pulled.

If such a pulling mechanism 223 is used, after the operation rod 223a is swung, that is, after the operation rod 223a is moved in one direction, the simple and easy-to-handle operation of making it move in the opposite direction can be strengthened. The tension generated by the front side wire ropes 21e, 21f.

The locking mechanism 224 functions to prevent the linear member 21 from being pulled out. As the lock mechanism 224, a structure capable of preventing the linear member 21 from being pulled in the winding direction may be employed. As shown in FIGS. 6 and 7 , a stopper 224f having a pawl 224d and a pawl 224e that engages with the pawl 224d is formed. The pawl 224d is supported on the rotation shaft 228 and is provided to rotate together with the rotation shaft 228 . The function of the stopper 224f is to prevent the rotation of the ratchet 224d by engaging the pawl 224e with the ratchet 224d to make it into a locked state. Moreover, in the locked state, since the rotation shaft 228 cannot rotate, the first and second pulleys 226a, 226b cannot rotate, and the pulling out of the front side wire ropes 21e, 21f is prevented.

The release mechanism 225 is used to release the locked state locked by the lock mechanism 224 . As the release mechanism 225, it is preferable to adopt a structure capable of maintaining the release state. As shown in FIG. 7 , the release mechanism 225 used in this embodiment is composed of a stopper 224f and an operating portion 225d that is annular and substantially L-shaped. The release mechanism 225 can release the engagement between the pawl 224e and the pawl 224d of the stopper 224f by pressing down the one end 225e of the operation portion 225d in the direction of gravity, and can maintain the release state. In other words, since the one end 225e of the operation portion 225d pressed down in the direction of gravity does not rotate in the direction against gravity without external force, the released state can be maintained. Therefore, according to the release mechanism 225, even if the hand operating the operation part 225d is removed, the release state is maintained and the lock state is not assumed. Therefore, when the linear member 21 is pulled out from the winding mechanism 22, one-handed operation can be adopted. .

As shown in FIG. 5, the take-up mechanism 22 has the same parts as the second rotor 221b used in Embodiment 1 and the spring 222 acting on the second rotor 221b. In the second rotor 221b, the rear side wire rope 21g is installed. , 21h, the rear side wire ropes 21g, 21h are wound on the second rotor 221b by the rotation of the second rotor 221b in one direction.

In addition, it is preferable to attach to the pulley 226 a cover body 229 (see FIG. 8 ) provided with an opening 229 a for inserting and withdrawing the linear member 21 . The cover 229 is mounted independently of the pulley 226 to prevent rotation as the pulley 226 turns. Thereby, although the pulley 226 rotates, the cover body 229 does not rotate, and therefore the opening part 229a has an opening shape at a fixed position normally. In this way, when the linear member 21 is drawn out from the pulley 226 and the linear member 21 is wound up by the pulley 226, the cover body 229 acts as a guide for the linear member 21, and the linear member 21 is smoothly drawn out from the pulley 226 or Winding up on the pulley 226 smoothly.

As shown in FIG. 5 , the take-up mechanism 22 of the vehicle seat fixing device 2 configured as above is attached to the lower portion of the armrests 1 a, 1 b of the vehicle seat 1 . In this way, by installing the take-up mechanism 22 on the lower part of the armrests 1a and 1b of the vehicle seat 1, the action point of the linear member 21 is not located at the lower part of the vehicle seat 1 but at the lower part of the armrests 1a and 1b. The effect of the linear part 21 is produced at a higher position on the vehicle seat 1 . Therefore, it is possible to generate a fixing force sufficient to resist a horizontal load and a vertical load (in particular, a load acting in a direction against gravity) applied to the vehicle seat 1 .

As shown in Figure 5, in this embodiment, the frame near the handrails 1a, 1b is provided with guides 24a, 24b having insertion holes for inserting the front side wire ropes 21e, 21f, and the front side wire ropes 21e, 21f are respectively Pull out from the guides 24a, 24b.

In addition, in this embodiment, a coiling mechanism 22 capable of coiling the front side steel wire ropes 21e, 21f and one of the rear side steel wire ropes 21g is provided at the lower part of one of the handrails 1a, and at the other handrail 1b, a coiling mechanism 22 capable of coiling only The take-up mechanism 22 of another rear side wire rope 21h. Like this, by being located at wherein one winding mechanism 22 of armrest 1a side, can be on the front side of vehicle seat 1, be connected to two linear parts 21 on the fixing part 3 by connecting part 23 (front side). Both the wire ropes 21e, 21f) can be coiled, and the operability is improved. In addition, it goes without saying that a coiling mechanism 22 capable of winding one of the front side wire ropes 21e and one of the rear side wire ropes 21g may also be provided at the bottom of one of the handrails 1a, and a coiling mechanism 22 capable of reeling up one of the front side wire ropes 21e and one of the rear side wire ropes 21g may be provided at the bottom of the other handrail 1b. The winding mechanism 22 which winds up another front side wire rope 21f and another rear side wire rope 21h.

The vehicle seat 1 of this embodiment is used as follows. That is, when the vehicle seat 1 is fixed on the floor, first, the rear side wire ropes 21g, 21h housed in the take-up mechanism 22 are drawn out, and the hook body 23g provided at the end thereof is attached to the rail member on the floor. 3a, 3b connection. Then, one end 225e of the operation portion 225d of the release mechanism 225 is pushed down in the direction of gravity to release the engagement between the pawl 224e and the pawl 224d of the stopper 224f. In this way, the locked state locked by the lock mechanism 224 is released, and the front side wire ropes 21e, 21f accommodated in the take-up mechanism 22 can be drawn out. Then, hold the handle 23f of the connecting member 23, draw out the front side wire ropes 21e, 21f accommodated in the winding mechanism 22, and hook the engaging portion 23e provided at the end of the connecting member 23 with the hook provided on the floor. 3c and 3d snap together. Finally, one end 225e of the operating portion 225d of the release mechanism 225 is pressed in the direction against gravity, and the pawl 224e of the stopper 224f is engaged with the pawl 224d. Accordingly, the lock mechanism 224 is operated to be in a locked state, and the withdrawal of the front side wire ropes 21e, 21f is prevented.

As described above, when the front wire ropes 21e, 21f and the rear wire ropes 21g, 21h are connected to the fixture 3 through the connection member 23, tension is generated in the front wire ropes 21e, 21f and the rear wire ropes 21g, 21h, respectively. That is, since the coiling mechanism 22 adopted in this embodiment has the spring 222 that applies torque in one direction to the rotating shaft 228 and the second rotor 221b, when the connection of the rear side wire ropes 21g, 21h is completed, the spring 222 Force and the second rotor 221b rotates in one direction, and guides the rear side wire ropes 21g, 21h to the winding direction. In addition, when the front side wire ropes 21e, 21f are connected, the force of the spring 222 makes the rotation shaft 228 rotate in one direction, and the first and second pulleys 226a, 226b rotate in one direction, and the front side wire ropes 21e, 21f rotate in one direction. Pulling in the winding direction. Therefore, in the state where the front side wire ropes 21e, 21f and the rear side wire ropes 21g, 21h are connected to the fixture 3 through the connecting member 23, the front side wire ropes 21e, 21f and the rear side wire ropes 21g, 21h does not slack, and the front side wire ropes 21e, 21f and the rear side wire ropes 21g, 21h generate tension.

When the force for fixing the vehicle seat 1 is further increased, the operating lever 223a constituting the pulling mechanism 223 is swung. Thus, the rotating shaft 228 rotates in one direction, and the first and second pulleys 226a, 226b rotate in this direction, thereby leading the front side wire ropes 21e, 21f to the winding direction. Therefore, the front side wire ropes 21e, 21f and The tension generated by the rear wire ropes 21g and 21h is further enhanced, so that the vehicle seat 1 can be firmly fixed.

In addition, at this time, when the clamping force of the coil spring 227 clamping the first and second pulleys 226a and 226b respectively reaches the limit, power transmission to the first and second pulleys 226a and 226b is stopped. Since the rotation of the first and second pulleys 226a, 226b is stopped, the same magnitude of tension can be generated on both the front side wire ropes 21e, 21f. In other words, for example, when the tension generated by one of the front side wire ropes 21e exceeds a predetermined value and the clamping force of the coil spring 227 reaches the limit, even if the rotating shaft 228 is rotated, the power cannot be transmitted to the first pulley 226a. Pulley 226a stops rotating. Then, at this time, if the tension generated by the other front side wire rope 21f does not reach a predetermined value, the second pulley 226b will continue to rotate to wind up the other front side wire rope 21f. Then, thereafter, when the tension generated by the other front side wire rope 21f exceeds a predetermined value and the clamping force of the coil spring 227 reaches the limit, even if the rotating shaft 228 is rotated, its power cannot be transmitted to the second pulley 226b. Therefore, the second Pulley 226b stops rotating. Therefore, the tension generated by one of the front side wire ropes 21e and the other front side wire rope 21f is equal in magnitude. In this way, the vehicle seat 1 can be fixed with good balance.

In addition, since an overload to the pulley 226 and the like can be prevented by the action of the coil spring 227, damage to the device can be prevented. In addition, by arbitrarily setting the clamping force of the coil spring 227, the tension generated by the linear member 21 can be set to a predetermined value.

According to the vehicle seat 1 of this embodiment, like the vehicle seat 1 in Embodiment 1, the take-up mechanism 22 is installed on the lower part of the armrests 1a, 1b, and the operating lever 223a is located at the hand of the vehicle seat user. Therefore, the vehicle seat user It is possible to manipulate the operation lever 223a by oneself. The same applies to the operation of the operation portion 225d of the release mechanism 225 and the extraction of the front wire ropes 21e, 21f and the rear side wire ropes 21g, 21h. Therefore, the user of the vehicle seat can perform the fixing work by himself. In addition, even if a helper (the purpose is only to provide help, including people other than companions) is required to fix the vehicle seat 1, the operation is easy, so the work load of the helper is greatly reduced.

According to this embodiment, since the connecting member 23 has the engaging portion 23c that engages with the fixing member 3, and the handle 23f provided with the engaging portion 23e at the end, the connecting member 23 can be attached to the fixing member by holding the handle 23f. 3 on. Therefore, for example, even if the body is not bent forward or backward, the connecting member 23 can be mounted on the fixing member 3, so the vehicle seat 1 can be fixed independently for the vehicle seat user whose upper body is difficult to bend. .

In addition, according to the vehicle seat 1 of the present embodiment, as in the first embodiment, it is only necessary to have the fixture 3 for connecting the linear members 21 via the connecting member 23 as the equipment on the floor side. The equipment on the floor side can be minimized, so the use environment of the vehicle seat 1 can be improved.
