Description

  The present invention relates to a structure of a vehicle seat provided in a passenger compartment of an automobile.

  Generally, in a seat structure of a vehicle such as an automobile, a front seat serving as a driver's seat or a passenger seat and a rear seat dedicated for passengers are provided in the vehicle interior at intervals in the vehicle front-rear direction.

Conventionally, when a passenger is not seated in the front seat, a structure of a vehicle seat that can use the front seat as a leg for a passenger in the rear seat has been proposed (for example, Patent Document 1). ).
In patent document 1, the leg part comprised so that folding was possible was provided in the seat surface part of the backseat sheet, and when a passenger | crew looks at a scene from the opening part of a roof panel, by raising a leg part, The position of the seating surface of the rear seat can be set to a high position. At this time, the passenger can use the seat back of the front seat as a leg rest.

Since the front seat 3 is used as a leg rest, the occupant of the rear seat 4 is inclined to the back surface 6d of the seat back portion 6 of the front seat 3 because the front seat 3 is used as a leg. Both the legs can be put along the seat, and the comfort of the occupant of the rear seat 4 is further improved.

[Second Embodiment]
Hereinafter, the structure of the vehicle seat which concerns on 2nd Embodiment of this invention is demonstrated, referring drawings.

  As shown in FIG. 2A, the vehicle according to this embodiment is a two-theta vehicle. Two seats 23 are provided on the floor surface 22 of the passenger compartment 21 at intervals in the vehicle width direction.

  As shown in FIG. 2A, the left seat (rear seat) 23 in the passenger compartment 21 extends upward from the seat surface portion 24 and the vehicle rear side end portion 24a of the seat surface portion 24 (see FIG. 3). And a seat back portion 25 formed as described above. Further, the vehicle compartment 21 is provided with a frame 26 that connects the upper position of the two seats 23 in the vehicle width direction. The frame 26 is provided at a position above the seat back portion 25 of each seat 23. A headrest portion 27 is provided.

  As shown in FIG. 2B, the left seat 23 is provided with a retractable sub-seat (front seat) 28. The sub seat 28 is attached to a seat surface portion 29, a seat back portion 30 disposed so as to stand up with respect to the seat surface portion 29, and an upper end portion 30 a of the seat back portion 30 so as to be slidable in the vertical direction. The headrest part 31 is provided.

  As shown in FIGS. 2A and 2B, the seat back portion 30 of the sub-seat 28 is rotatably connected to the seat 23 via a rotation shaft 32 (see FIG. 3). The 28 seat back portions 30 are configured to be able to be tilted forward toward the front of the vehicle with a pivot shaft 32 as a center. Further, on both sides of the seat back portion 30 of the sub seat 28 in the vehicle width direction, notches 33 are provided from the intermediate portion 30b to the lower end portion 30c in the vertical direction of the seat back portion 30.

  As shown in FIG. 3, the left seat 23 is provided with a recess 34 that opens to the front of the vehicle between the seat surface portion 24 and the floor surface 22. The seat surface portion 29 of the sub seat 28 is attached to the seat 23 via a guide rail or the like (not shown), and the seat surface portion 29 moves between the recess 34 and the floor surface 22 along the guide rail. It is like that.

  When the sub-seat 28 is stored in the seat 23, the seat surface portion 29 is moved toward the recess 34 so as to enter the vehicle rear side of the seat back portion 30 while rotating the seat back portion 30 around the rotation shaft 32. Move. As a result, as shown in FIG. 3, the seatback portion 30, the seat surface portion 29, and the vehicle front-rear direction are stored in the recess 34.
