In this case, as shown in FIG. 2, the rear end portion of the front-rear direction extending portion 22 a reaches the fifth wire 25 that constitutes the rear edge portion of the wire frame 20 extending in the vehicle width direction, and the fifth point is at the intersection. The wire 25 is combined and integrated.

  The outer base portion of the two U-shaped base portions of the downward projecting portion 21b of the first wire 21 is bent substantially rearward (more specifically, obliquely rearward toward the outside of the vehicle), and substantially rearward in the vehicle front-rear direction. An extending rearward extension (second extension) 21a is formed. Moreover, the 3rd wire 23 has passed the back vicinity of the downward protrusion part 21b. The third wire 23 and the rear extension 21a of the first wire 21 intersect in the vicinity of the rear of the downward projecting portion 21b (more specifically, the vicinity of the rear of the vehicle relatively outside), and are coupled and integrated at the intersection. (Joint part W) [Composition of Claim 3].

  Thus, the 1st extension part 21c of the 1st wire 21 is extended ahead, and the intersection with the vehicle width direction extension part 22b of the 2nd wire 22 is located in the front vicinity of the downward projection part 21b. Further, the second extension portion 21a of the first wire 21 extends substantially rearward, and the intersection with the third wire 23 is located relatively near the rear rear of the lower protruding portion 21b. Furthermore, the longitudinal extension 22a of the second wire 22 and the third wire 23 intersect with each other in the vicinity of the rearward side of the downward projecting portion 21b relatively inside the vehicle, and are joined and integrated at the intersection (joint portion W). [Configuration of claim 4].

  FIG. 5 is a longitudinal sectional view of the front lock portion 32 as viewed from the front, and FIG. 6 is a longitudinal sectional view as viewed from the side. A resin clip 50 (see FIG. 3) for attaching the front portion of the seat cushion 15 to the vehicle body is fitted into an opening formed on the upper surface of the floor panel rear 12 immediately after the kick-up portion 12a. Then, the downward projecting portion 21 b of the wire frame 20 projecting downward from the front lower surface of the foamed resin pad 40 is pressed into the resin clip 50 on the lower surface of the pad 40 and press-fitted. Thereby, the front portion of the seat cushion 15 is fixed to the floor panel rear 12. In this case, after the seat cushion 15 is attached, the front lock portion 32 including the downward projecting portion 21b and the resin clip 50 is hidden by the seat cushion 15 and cannot be seen. It does not impair the merchantability of the vehicle.

  Next, the operation of this embodiment will be described. For example, when this vehicle has a frontal collision or the like, a forward load is applied to the seat cushion 15 as indicated by an arrow i in FIG. At this time, since the front part of the cushion 15 is fixed by the front lock part 32, the cushion 15 as a whole is bent or deformed back and forth, so that the rear stopper part 31 moves forward from the lower end part of the seat back 16. To escape. Then, the rear stopper portion 31 does not function as a stopper, and as shown by an arrow ii in FIG. 3, a forward moment of rotation about the front lock portion 32 acts on the seat cushion 15, and as a result, the front There is a possibility that the part lock part 32 is in a bottle open state and is greatly deformed or damaged.

  However, in the present embodiment, the first extension portion 21c extending forward in the vehicle front-rear direction is formed on the inner base portion of the two base portions of the downward protruding portion 21b of the first wire 21 belonging to the front lock portion 32. The first extending portion 21c and the vehicle width direction extending portion 22b of the second wire 22 extending in the vehicle width direction intersect with each other in the vicinity of the front of the lock portion 32 and are integrated at the intersection (FIG. 2, refer to FIG. 4). Thus, even if the seat cushion 15 is subjected to a rotational moment forward upward about the front lock portion 32 and the front lock portion 32 is in the bottle open state, The first extension portion 21c of the one wire 21 is stretched in the front-rear direction in the vicinity of the front lock portion 32, and the rigidity or strength in the front-rear direction of the front lock portion 32 is improved. As a result, the front lock portion 32 is greatly increased. Na Shapes and breakage can be suppressed, it is possible to prevent the front falling off of the seat cushion 15.

  In addition to the vehicle width direction extension portion 22b integrated with the first extension portion 21c of the first wire 21, the inner end portion of the vehicle width direction extension portion 22b is bent to the second wire 22 in the vehicle longitudinal direction. The front / rear extension 22a is formed so as to extend to the front (see FIG. 2 and FIG. 4). As a result, the rigidity or strength of the front lock portion 32 in the front-rear direction is further improved.

  In this case, the rear end portion of the second wire 22 in the front-rear direction extending portion 22a is fixed to the fifth wire 25 constituting the rear edge portion of the wire frame 20 extending in the vehicle width direction (see FIG. 2). This also improves the mounting rigidity of the pad 40.

  Furthermore, the first base 21 on the outer side of the lower protruding portion 21b of the first wire 21 belonging to the front lock portion 32 has a second base extending rearward in the vehicle front-rear direction substantially opposite to the first extension 22c. 2 The extension portion 21a is formed, and the second extension portion 21a and the third wire 23 extending in the vehicle width direction are crossed in the vicinity of the rear of the lock portion 32 and integrated at the intersection (FIG. 2, Accordingly, in addition to the first extension portion 21c, the second extension portion 21a is also stretched in the front-rear direction in the vicinity of the front lock portion 32 with respect to the rotational moment forward upward (and That position is on the opposite side of the first extension portion 21c with the front lock portion 32 interposed therebetween, and the rigidity or strength of the front lock portion 32 in the front-rear direction is further improved.

  Further, an integrated intersection of the first extension portion 21c of the first wire 21 and the vehicle width direction extension portion 22b of the second wire 22 is disposed in front of the front lock portion 32, and the first wire 21 The intersection of the two extension portions 21a and the third wire 23 is disposed at the rear of the front lock portion 32 relatively outside the vehicle, and the longitudinal extension portion 22a of the second wire 22 and the third wire 23 Since the integrated intersections are arranged relatively rearward of the front lock portion 32 (see FIG. 4), the three intersections are scattered around the front lock portion 32. Thus, the rigidity or strength of the front lock portion 32 in the front-rear direction is further improved.

  The wire frame 20 is provided with a rear projecting portion 21d projecting rearward from the pad 40, that is, a rear stopper portion 31 at the rear portion in the vehicle front-rear direction. Therefore, the seat cushion 15 can be attached in a shortened manner, and the rear stopper portion 31 can be removed from the lower end of the seat back 16 and removed. Even if the seat cushion 15 is subjected to a forward upward rotational moment about the front lock portion 32 and the front lock portion 32 is in the bottle open state, the rigidity or strength of the front lock portion 32 in the front-rear direction As a result, large deformation and breakage of the front lock portion 32 can be suppressed, and the seat cushion 15 can be prevented from falling forward.

  The front lock portion 32 is located in front of the other part at the front edge of the seat cushion 15, but this portion is located between both legs of the seated occupant. The seating ability will not be reduced.

  The above embodiment is the best embodiment of the present invention, but it goes without saying that various modifications and changes may be made without departing from the scope of the claims. For example, in the above-described embodiment, the wire frame 20 is made of five types of wires 21 to 25. However, the wire frame 20 may be made of a smaller number of wires, and in that case, an intersection point where the wires cross each other is one. A continuous wire may be formed by bending. In the above-described embodiment, the rear stopper portion 31 is manufactured at the rear end portion of the first wire 21. However, the rear stopper portion 31 can be manufactured using another wire, for example, a part of the fifth wire 25. Moreover, in the said embodiment, although the downward protrusion part 21b was bent in U shape by front view, you may bend in U shape by side view, for example. In the above embodiment, the inner base portion of the two U-shaped base portions of the downward projecting portion 21b is bent forward and connected to the front extension portion, and the outer base portion is bent rearward and the rear extension portion. However, conversely, the inner base portion may be bent backward and connected to the rear extension portion, and the outer base portion may be bent forward and connected to the front extension portion. Alternatively, both bases can be bent forward and connected to the front extension, or both bases can be bent back and connected to the rear extension, or only one of the bases can be forward It may be bent and connected to the front extension, or it may be bent backward and connected to the rear extension.

  As described above in detail with reference to specific examples, the present invention increases the rigidity or strength of the front cushion portion of the seat cushion in the front-rear direction, even if the stopper of the seat cushion rear portion is released. In the technical field of improving the seat structure for a vehicle, more specifically, the wire frame built in the seat cushion, since it is possible to prevent the deformation or breakage of the lock part or the seat cushion from falling off.
