In addition, shown in Fig. 3 B and 4A, when the second back seat 5b (5a) towards the compartment 2 inwardly during swing---when the second back seat 5b (5a) moves when avoiding contacting with rear wheel cover 1a, connecting panel 33 also moves along with the mobile of the second back seat 5b (5a).Therefore, contact with rear wheel cover 1a along with the second back seat 5b (5a) moves avoiding, the connecting pin 34a of first connecting rod 34 is spurred by connecting panel 33, and first connecting rod 34 rotates along the clockwise direction among Fig. 3 A then.Along with clockwise rotating of first connecting rod 34, first connecting rod 35 by interlocking cable 36 along the anticlockwise motion among Fig. 3 A.So second connecting rod 37 is promoted by first connecting rod 34 and 35 respectively and rotates along direction B shown in Figure 2.Thereby the bottom 37b of each second connecting rod 37 moves up, and causes each second connecting rod 37 and each restriction projection 31 to break away from.That is to say,,, eliminated the restriction that the second back seat 5b (5a) is moved backward in the vehicle fore-and-aft direction along with dodging of the second back seat 5b (5a) is mobile when the second back seat 5b (5a) moves to can avoid with rear wheel cover 1a position contacting the time.Thereby, shown in Fig. 4 B, realized further moving backward of second back seat 5b (5a) 2 rear portions towards the compartment.In addition, shown in Fig. 4 B, the 3rd row's seat 6 is contained in the below of floor compartment 3.When the 3rd row's seat 6 when being contained in the below of floor compartment 3, second series seat 5 becomes and is movable to position after leaning on most.

Second series seat 5 is being moved in the process of the position after leaning on most, the first and second back seat 5a and 5b toward the outer side, promptly along each first and second back seat 5a and 5b toward each other back to direction.Thereby although the gap turn narrow between the first and second back seat 5a and the 5b, the leg that is sitting in the occupant on back seat 5a and the 5b respectively can not contact with each other substantially.In addition, because the position that second series seat 5 moves to after leaning on most, so formed personal space, it has effectively utilized the space between first row's seat 4 and the second series seat 5.

On the other hand, as shown in Figure 5, second series seat 5 is being moved in the process of the anterior position in the vehicle fore-and-aft direction, the first and second back seat 5a and 5b can rotate along the direction that the first and second back seat 5a and 5b are faced with each other by outside swing.Thereby, can promote to be sitting in respectively the interchange between the occupant on the first and second back seat 5a and the 5b.In addition, when second series seat 5 moves forward, the first and second back seat 5a and 5b are spaced-apart, and this makes and prevented that the leg that is sitting in the occupant on the first and second back seat 5a and the 5b respectively from contacting with each other, and has also formed the path that leads to the 3rd row's seat 6 roomily.

According to the seat system that be used for vehicle relevant, can realize following effect and benefit with first embodiment.

Because first and second back seat 5a of formation second series seat 5 and 5b edge respectively are the arc swing at center with fulcrum Oa and Ob, so when the first and second back seat 5a and 5b move to the rear positions in compartment 2 backward, by making the first and second back seat 5a and 5b along its direction adjacent to each other---i.e. 2 inside directions---towards the compartment swing, the first and second back seat 5a can not contact with corresponding rear wheel cover 1a substantially with 5b.Thereby, fully guaranteed each first and second back seat 5a and the amount of movement of 5b in the fore-and-aft direction of vehicle.In addition, in the seat system of first embodiment, first and second slide rails 7 and 8 need not be provided with obliquely with respect to the fore-and-aft direction of vehicle.The first and second back seat 5a and 5b can not contact with each other when mobile backward, maintain the gap that is formed at when it is positioned anterior position therebetween simultaneously.In addition, as the first and second back seat 5a and 5b during, can promote to sit respectively the interchange between the occupant thereon along the direction swing that faces with each other.Thereby, realized various seat arrangement by the seat system that is used for vehicle with high practicability with simple structure.

Each fulcrum Oa and the Ob of each first and second back seat 5a and 5b set more more forwardly than the anterior position of each first and second back seat 5a and 5b.Therefore, when the first and second back seat 5a and 5b were positioned at the rear position, each first and second back seat 5a and 5b be 2 the inboard towards the compartment a little.Therefore, when the first and second back seat 5a and 5b are positioned at the rear position, formed the personal space that is used for being sitting in respectively the occupant on the first and second back seat 5a and the 5b roomily.So, can improve occupant's comfort level.

Each first and second back seat 5a and 5b are by each support in the paired pendulum rail.In the pendulum rail each is all formed by 21 pairs on bottom rail and 23 pairs on last pendulum rail in pairs.Thereby each first and second back seat 5a and 5b stably swing along vehicle-width direction.

When each first and second back seat 5a and 5b are mobile backward under itself and rear wheel cover 1a state of contact, if each first and second back seat 5a and 5b further move backward along each first and second track 7 and 8 of straight layout on the fore-and-aft direction of vehicle, then each first and second back seat 5a and 5b move backward its with just limit before corresponding rear wheel cover 1a contacts by corresponding mobile limiting mechanism 30.Therefore, can prevent reliably because each first and second back seat 5a contacts the destruction of being caused with 5b with corresponding rear wheel cover 1a.In addition, when each first and second back seat 5a and 5b move to not can be with rear wheel cover 1a position contacting (preventative moving) time, along with the preventative of each back seat 5a and 5b moves, eliminated by each and moved the restriction that limiting mechanism 30 causes moving backward along the vehicle fore-and-aft direction.Thereby, fully guaranteed the amount of movement of each first and second back seat 5a and 5b.In addition, various seat arrangement have been realized with high practicability.In addition, prevented that reliably each first and second back seat 5a from contacting with each rear wheel cover 1a with 5b.

Along with the preventative of each first and second back seat 5a and 5b moves, first connecting rod 34 and 35 and second connecting rod 37 interlockings.Each back seat 5a and 5b be about to each rear wheel cover 1a state of contact under, second connecting rod 37 with limit projection 31 accordingly and engage.On the other hand, when each back seat 5a and 5b be in its not with each rear wheel cover 1a state of contact following time, second connecting rod 37 breaks away from corresponding restriction projection 31.Thereby by adopting mechanical mobile limiting mechanism 30, each first and second back seat 5a of restriction/permission and 5b's moves backward reliably.

Can carry out following change and modification to the seat system of first embodiment.

Each the first and second back seat 5a and 5b that forms the second series seat does not need to be set at along being the rotation arc swing at center with each center-point Oa and Ob, and wherein each described center-point is set in the place ahead in the fore-and-aft direction of vehicle.For example, as shown in Figure 6, each first and second back seat 5a and 5b can be set at along being the rotation arc swing at center with each center-point Od and Oc, wherein each described center-point is set in the rear of each back seat 5a and 5b.For example, each center-point Od and Oc can be set in the position of arranging each the 3rd row's seat.When center of oscillation point Od and Oc were set in the rear of back seat 5a and 5b respectively, back seat 5a and 5b faced one another when moving to the rear position a little, shown in Fig. 7 A.Therefore, the position moving backward can promote and strengthen to be sitting in respectively the interchange between the occupant on the first and second back seat 5a and the 5b.In addition, shown in Fig. 7 B, when the second back seat 5b was positioned at anterior position, by swinging the second back seat 5b towards inlet 1b, the passenger can easily take/leave the second back seat 5b.So, can further improve the practicality of described seat system.

The center of turn of each first and second back seat 5a and 5b does not need as set independently for example shown in Figure 5ly, on the contrary, for example can only be one fulcrum in the line midpoint setting of center-point Oa and Ob.

[second embodiment]

Below Fig. 8 to 13 is with reference to the accompanying drawings illustrated the seat system relevant with second embodiment.

As shown in Figure 8, the first row's seat 4 that comprises driver's seat 4a and passenger seat 4b is arranged in the position, forefront on the floor compartment 3 in the compartment 2 of vehicle 1 along vehicle-width direction.The second series seat 5 that comprises the first back seat 5a and the second back seat 5b is arranged side by side in first row's seat, 4 rears mutually.In addition, comprise the 3rd back seat 6a and the 4th back seat 6b the 3rd row seat 6 be arranged side by side in mutually second series seat 5 along the rear on the vehicle fore-and-aft direction.

A pair of first slide rail 7 (first rail structure) is set, thereby it can move it as sliding track mechanism along the fore-and-aft direction of vehicle to be used to the supporting first back seat 5a on floor compartment 3.Similarly, a pair of second slide rail 8 (second rail structure) is set on floor compartment 3, thereby it can move it as sliding track mechanism along the fore-and-aft direction of vehicle to be used to the supporting second back seat 5b.Every pair first and second slide rail 7 and 8 fore-and-aft direction with respect to vehicle on floor compartment 3 extends obliquely, makes it anterior spaced-apart very wide and its rear portion is drawn close mutually.In other words, the first and second pairs of slide rails 7 and 8 are arranged on the floor compartment 3, make its front end extend to open along vehicle-width direction its rear end and extend with on the line of centers that extends along the vehicle fore-and-aft direction that converges in vehicle.So, when each first and second back seat 5a and 5b are positioned at as shown in Figure 8 anterior position, have enough spaces betwixt.First slide rail 7 is identical with the setting second back seat 5b thereon with second slide rail 8 with the structure that the first back seat 5a thereon is set.Therefore, as example the 26S Proteasome Structure and Function of described seat system is described hereinafter with reference to second slide rail 8 and the second back seat 5b, unless otherwise noted.In addition, the reference number in the bracket is represented the appropriate section of first slide rail 7 and the setting first back seat 5a thereon.

As shown in Figure 9, by playing the last rail 10 that moves forward and backward mechanism's effect and playing the seat rotation maintaining body 40 of preventing the contact mechanism effect the second back seat 5b (5a) is arranged on second slide rail 8 (7).More particularly, rail 10 comprises by rolling element 11 (not shown) and is arranged on pedestal 12 on each second slide rail 8 (7) on each, but makes pedestal 12 green phases for roll described rolling elements 11 and move in the fore-and-aft direction of vehicle along each second slide rail 8 (7) of each slide rail 8 (7).

With predetermined interval a plurality of conjugate foramen 8a (7a) are set by each second slide rail 8 (7).Pedestal 12 is provided with any junction surface that engages 13 with a plurality of conjugate foramen 8a (7a).Therefore, last rail 10 limits with any junction surface that engages 13 among a plurality of conjugate foramen 8a (7a) along moving by each of vehicle fore-and-aft direction.So the second back seat 5b (5a) locatees regularly.

Slide bar 14---it can rotate along the direction of arrow A shown in Figure 9---is formed at the front end place along the vehicle fore-and-aft direction of pedestal 12, thereby connects the front end of pedestal 12.When operation slide bar 14, move along the direction that makes junction surface 13 with re-spective engagement hole 8a (7a) disengaging by the connecting rod mechanism (not shown) at junction surface 13.Therefore, junction surface 13 breaks away from corresponding conjugate foramen 8a (7a), and upward rail 10 becomes and can move along the fore-and-aft direction of vehicle.

Seat rotates maintaining body 40 and is arranged between the second back seat 5b (5a) and the pedestal 12.As shown in figure 10, seat rotates maintaining body 40 and comprises and ringwisely be fixed on first top base 42 on bottom base 41 on the pedestal 12, the ringwise lower surface that is fixed on the second back seat 5b (5a) and ringwisely be fixed on second top base 44 on first top base 42 by calking pin 43.

First top base 42 is arranged in the top, and second top base 44 is arranged in below, and bottom base 41 is kept by first and second top bases 42 and 44.In addition, ringwise first rolling element 45 is set between the bottom base 41 and first top base 42.Ringwise second rolling element 46 is set between the bottom base 41 and second top base 44.Thereby first and second top bases 42 and 44 can rotate with respect to bottom base 41.

Control lever 49 remains on second top base 44 by pin 47 and spring 48, thereby can rotate with respect to second top base 44.On control lever 49, form pinning 49a.In addition, the control lever 49 and second top base 44 are attached, make pinning 49a pass through spring 48 bias voltages to bottom base 41a.More particularly, the outer peripheral face at bottom base 41 is provided at predetermined intervals a plurality of lock holes 50 (the first lock hole 50a, the second lock hole 50b, the 3rd lock hole 50c and the 4th lock hole 50d).Spring 48 is along any the direction biases operative lever 49 that engages that makes pinning 49a with lock hole 50a, 50b, 50c and 50d.When locking rod 49 was in pinning 49a and orientates any cooresponding position with lock hole 50a, 50b, 50c and 50d as, pinning 49a engaged with any of lock hole 50a, 50b, 50c and 50d.In this embodiment, the first lock hole 50a is set at the second back seat 5b (5a) corresponding with pinning 49a during as shown in Figure 1 towards the place ahead of vehicle fore-and-aft direction.In addition, shown in Figure 12 A, the second lock hole 50b is set at the second back seat 5b (5a) corresponding with pinning 49a during towards the direction identical with the bearing of trend of second slide rail 8 (7).The 3rd lock hole 50c be set at the second back seat 5b (5a) a little towards the compartment 2 when inboard---when each first and second back seat 5a and 5b face one another a little---49a is corresponding with pinning.The 4th lock hole 50d be set to the second back seat 5b (5a) than the bearing of trend of second slide rail 8 (7) more outwardly the time---shown in Figure 13 B---49a is corresponding with pinning.

Be used to limit the below that mobile limiting mechanism 60 that each first and second back seat 5a and 5b move backward is arranged on each first and second back seat 5a and 5b.More particularly, mobile limiting mechanism 60 comprises and is arranged on the restriction projection 61 that each second slide rail 8 (7) locates and is arranged on the mutual interlocking gear 62 that the second back seat 5b (5a) locates.The symmetrical mobile limiting mechanism 60 of same structure is set below the first and second back seat 5a and 5b respectively.Thereby the mobile limiting mechanism 60 that below will be arranged on second back seat 5b below illustrates the 26S Proteasome Structure and Function of mobile limiting mechanism 60 as example.In addition, omitted last rail 10 among Figure 11 A.

Equally shown in Figure 11 B, each restriction projection 61 forms bevelled projections, thereby forms the abrupt slope on the surface forward and form the gentle slope on the surface backwards.The restriction projection 61 of said structure is arranged on each on the orbit element that forms second slide rail 8.

Mutual interlocking gear 62 comprises: plate shape connecting panel 63, and it is arranged on the upper surface of first top base 42; Interlocking cable 64, one end and interlock board 63 are connected in respect to the fulcrum O of first top base 42 along the vertical positions of symmetry of interlock board 63; A pair of first connecting rod 65, it is supported on the lower surface of bottom base 41 with near the position of rotating mode each second slide rail 8, and the other end of described each interlocking cable 64 is connected to described first connecting rod 65; And a pair of second connecting rod 66, it is supported on the internal face of corresponding pedestal 12 in rotating mode.

Each first connecting rod 65 is made by forming L shaped sheet material basically, and sentence on the lower surface that rotating mode is supported on bottom base 41 at the kink of each first connecting rod 65, make the one end rotate the inboard of maintaining body 40 and its other end rotates the outside of maintaining body 40 towards seat towards seat.Thereby each first connecting rod 65 forms and can rotate in the horizontal direction of vehicle.In addition, each interlocking cable 64 is connected in the inner end place towards seat rotation maintaining body 40 inboards of each first connecting rod 65.More specifically, be connected with interlock board 63 in the position that is positioned at first top base, 42 fulcrum O with the other end of a first connecting rod 65 that is arranged in outer fix (being arranged in left side first connecting rod 65 among Figure 11) bonded assembly interlocking cable 64 along the rear of vehicle fore-and-aft direction.In addition, be connected with interlock board 63 in the place ahead of fulcrum O with another other end that is arranged in first connecting rod 65 (being arranged in right side first connecting rod 65 among Figure 11) the bonded assembly interlocking cable 64 of inner side along the vehicle fore-and-aft direction.Thereby when the anticlockwise motion of first top base 42 in Figure 11, interlocking cable 46 is connected plate 63 pullings.So each first connecting rod 65 all rotates, make outer end that seat rotates maintaining body 40 move forward along the fore-and-aft direction of vehicle.

Shown in Figure 11 B, each second connecting rod 66 is supported on the internal face of each pedestal 12 in rotating mode equally, thereby is positioned at the top of each second slide rail 8.Each second connecting rod 66 is made by forming L shaped sheet material basically, and its kink is supported on each pedestal 12.In addition, the upper end 66a of each second connecting rod 66 projects upwards and contacts with each first connecting rod 65 from each pedestal 12.The lower end 66b of each second connecting rod 66 is positioned on the lower surface of each second slide rail 8.In addition, the support portion of each second connecting rod 66 is provided with for example biasing member 67 of coil spring etc., makes each second connecting rod 66 all the time along the clockwise direction bias voltage of Figure 11 B.In addition, second connecting rod 66 is arranged as: when the second back seat 5b in the second back seat 5b may with form under the outstanding rear wheel cover 1a state of contact in compartment 2 when mobile backward, second connecting rod 66 limits projection 61 at the second back seat 5b and an anterior position place before the rear wheel cover 1a contact position and contacts with each.In addition, one of at least the first and second back seat 5a and 5b represent such state with corresponding rear wheel cover 1a state of contact: for example the first back seat 5a shown in Figure 12 A forward state or for example as shown in FIG. 13A the first and second back seat 5a and 5b towards the compartment state of 2 inboards to face one another a little.In other words, the at least the first and second back seat 5a represent such state with one of 5b with corresponding rear wheel cover 1a state of contact: for example the second back seat 5b is along portable cord L2, and---described portable cord L2 guides the second seat 5b to contact with rear wheel cover 1a---advances, rather than---described portable cord L1 does not guide the second back seat 5b to contact with rear wheel cover 1a---advances along portable cord L1.

When the second back seat 5b the second back seat 5b may with rear wheel cover 1a state of contact under further along the vehicle fore-and-aft direction when mobile backward, the lower end 66b of each second connecting rod 37 the second back seat 5b with contact with each restriction projection 31 before rear wheel cover 1a contacts.So the second back seat 5b is restricted along the amount that the vehicle fore-and-aft direction moves.

In addition, when the second back seat 5b rotates with the direction of extending with slide rail 8 when parallel to the outside of vehicle 1 shown in Figure 12 A, the pinning 49a of control lever 49 shown in Figure 10 engages with the second lock hole 50b on being arranged on bottom base 41, though make the second back seat 5b be fixed on the second back seat 5b when further mobile backward also not with rear wheel cover 1a position contacting place.In other words, the second back seat 5b is fixed in a pivot angle place, makes the second back seat 5b advance along portable cord L1 when further mobile backward.Along with the rotation of the second back seat 5b, connecting panel 63 is along the anticlockwise motion among Figure 11 A, and this further spurs interlocking cable 64.So each first connecting rod 65 rotates, make outer end that seat rotates maintaining body 40 move forward along the fore-and-aft direction of vehicle.Thereby by the operation of first connecting rod 65 outer ends, each connecting rod 66 is along the anticlockwise motion of Figure 11 B, and the upper end 66b of each second connecting rod 66 moves up then.So second connecting rod 66 breaks away from each restriction projection 61.In other words, when the second back seat 5b turns to the second back seat 5b not with rear wheel cover 1a position contacting,, eliminated the restriction that the second back seat 5b is moved backward along with dodging of the second back seat 5b is mobile.Thereby shown in Figure 12 B, back seat 5b (5a) becomes and can further move towards vehicle rear-side.In addition, shown in Figure 12 B, the 3rd row's seat 6a is placed in the below of floor compartment 3.When the 3rd row's seat when being placed in the below of floor compartment 3, the second series seat becomes and is movable to position after leaning on most in the compartment 2.

When position that second series seat 5 moves to after leaning on most, the first and second back seat 5a and 5b mutually back to, promptly shown in the dotted line among Figure 12 B a little towards the outside of vehicle.Thereby although shortened distance between the first and second back seat 5a and the 5b, the leg that is sitting in the occupant on the first and second back seat 5a and the 5b respectively can not contact with each other substantially.In addition, formed the personal space that effectively utilizes the space between first row's seat 4 and the second series seat 5.In addition, shown in the solid line among Figure 12 B, each first and second back seat 5a and 5b are rotatable with towards the place ahead.

On the other hand, as shown in FIG. 13A, when the first and second back seat 5a and 5b were under the situation of anterior position of vehicle fore-and-aft direction to compartment 2 inboard rotations at second series seat 5, the pinning 49a of control lever 49 shown in Figure 10 engaged with the 3rd lock hole 50c on being arranged on bottom base 41.Therefore, the first and second back seat 5a and 5b are configured to be positioned on the position that the first and second back seat 5a and 5b face one another a little.Thereby, can strengthen and promote being sitting in respectively the interchange between the occupant on the first and second back seat 5a and the 5b.In addition, when the first and second back seat 5a and 5b move to the anterior position place, the first and second back seat 5a and 5b are spaced-apart.So, prevented that the leg that is sitting in the occupant on the first and second back seat 5a and the 5b from contacting with each other, and further fully guaranteed to lead to the path of the 3rd row's seat 6.

On the other hand, shown in Figure 13 B, when the second back seat 5b that is positioned at anterior position when the inlet 1b that is arranged on vehicle one side rotates, the pinning 49a of control lever 49 engages with the 4th lock hole 50d on being arranged on bottom base 41.Thereby the passenger can easily take/leave the second back seat 5b, and has further improved the practicality of described seat system.

In addition, the first back seat 5a operates in the mode identical with the second back seat 5b.Thereby the first back seat 5a has identical functions and effect.

According to second embodiment, can realize following effect and benefit.

Each slide rail 7 and 8 that forms rail structure is arranged on the floor compartment 3, makes first and second slide rails 7 and 8 front portions towards vehicle separate, and makes first and second slide rails 7 and 8 draw close mutually towards the rear portion of vehicle.Therefore, the first and second back seat 5a when being positioned at anterior position and 5b be separated, and the first and second back seat 5a and 5b draw close mutually when being positioned at the rear position.Thereby, when back seat 5a and 5b are mobile backward, thus the first and second back seat 5a and 5b substantially not can be formed on floor compartment 3 accordingly on contact to the outstanding rear wheel cover 1a in compartment 2.In addition, each first and second back seat 5a and 5b support in rotating mode by rotating maintaining body 40, and each first and second back seat 5a remains in the following state with 5b: each back seat 5a and 5b towards with the identical direction of bearing of trend of each first and second slide rail 7 and 8.In other words, each first and second back seat 5a and 5b remain on each back seat 5a and 5b towards the state identical with its moving direction.Therefore, the outward flange of each first and second back seat 5a and 5b advances along moving direction, makes the outward flange of each first and second back seat 5a and 5b can not contact with rear wheel cover 1a substantially.Thereby, when second series seat 5 is positioned at anterior position, fully guarantee the gap between the first and second back seat 5a and the 5b, and fully guaranteed its amount that moves along the vehicle fore-and-aft direction.So described seat system with simple structure has been realized various seat arrangement with high practicability.

The first and second back seat 5a and 5b can remain on back seat 5a and 5b on the position of 2 inboards, compartment, and this has allowed the occupant who sits thereon respectively to be easier to face one another.So, can promote and strengthen to be sitting in respectively the interchange between the occupant on the first and second back seat 5a and the 5b.

Each first and second back seat 5a and 5b rotate and remain on each back seat 5a and 5b on the position of inlet 1b.Thereby the passenger can easily take/leave each first and second back seat 5a and 5b.

When each first and second back seat 5a and 5b are further mobile backward under each back seat 5a and 5b and corresponding rear wheel cover 1a state of contact, each back seat 5a and 5b move backward each back seat 5a and 5b with just limit before corresponding rear wheel cover 1a contacts by mobile limiting mechanism 60.Thereby, can prevent reliably and avoid because each first and second back seat 5a and 5b contact the destruction of being caused with rear wheel cover 1a accordingly.In addition, when thereby each first and second back seat 5a and 5b rotate when being in each first and second back seat 5a and 5b not with corresponding rear wheel cover 1a position contacting, in response to the rotating operation of each back seat 5a and 5b, eliminated the restriction that causes by mobile limiting mechanism 60 to moving backward.Thereby, fully guaranteed the amount of movement of each first and second back seat 5a and 5b, and prevented reliably that further each back seat 5a from contacting with each corresponding rear wheel cover 1a with 5b.

Along with dodging of each first and second back seat 5a and 5b is mobile, first connecting rod 65 and second connecting rod 66 operations.When each back seat 5a and 5b were in each back seat 5a and 5b and corresponding rear wheel cover 1a state of contact, second connecting rod 66 engaged with restriction projection 31 respectively.On the other hand, when each back seat 5a and 5b were in each back seat 5a and 5b not with each rear wheel cover 1a state of contact, second connecting rod 66 broke away from restriction projection 31 respectively.Thereby, by each first and second back seat 5a and 5b application machine are moved limiting mechanism 60, limit and allow moving backward of each back seat 5a and 5b reliably.

Can carry out following change and modification to the seat system that be used for vehicle relevant with this embodiment.

The seat system that be used for vehicle relevant with first embodiment can have first and second slide rails 7 and 8, and its slide rail 7 and 8 the same fore-and-aft directions that are arranged as with respect to vehicle with the seat system that is used for vehicle of being correlated with second embodiment extend obliquely.
