Abstract

PROBLEM TO BE SOLVED: To reduce the number of part items, to reduce weight, and to enable a stiffener between legs to hold rigidity by fixing the stiffener between a pair of left/right legs, and installing a finisher on this stiffener. SOLUTION: A longitudinally sliding mechanism 3 of a seat cushion has respectively a pair of left/right fixing rails 5 and a longitudinally slidable movable rail 7. Front/rear legs 8, 8 are respectively fixed to a pair of left/right fixing rails 5 by a bolt 8a, and these legs 8, 8 are formed long in the length so that a sitting surface of a seat cushion becomes high. A stiffener 31 is fixed between upper parts of a pair of left/right legs 8, 8 by a fixing means such as a bolt 33. A finisher 35 integral with a leg cover 41 is fastened to the stiffener 31 by a machine screw 37. Thus, the number of part items can be reduced, weight can be reduced, and the stiffner between the legs can hold rigidity.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat and, more particularly, to a vehicle seat having a pair of right and left front and rear slide mechanisms each having a fixed rail and a movable rail, wherein a leg is provided at an end of the fixed rail of the front and rear slide mechanism. The present invention relates to a vehicle seat in which a cushion frame of a seat cushion is fixed to a movable rail via a cushion bracket.

[0002]

2. Description of the Related Art Conventionally, a vehicular seat has been configured so that it can be moved back and forth by a back and forth slide mechanism having a fixed rail and a movable rail. As shown in FIG. 7, the front / rear slide mechanism 3 of the seat cushion 1 has a fixed rail 5 and a movable rail 7, and the fixed rail 5 is attached to the floor of the vehicle body via front and rear legs 8,8. The front and rear slide mechanism 3 can operate a lock mechanism of the movable rail 7 by operating the operation lever 9.

[0003] A vertical wall 7a is formed on the movable rail 7,
A cushion bracket 11 for mounting a seat cushion is fixed to the vertical wall 7a at front, rear, left and right positions. The cushion frame 17 is fixed to the cushion bracket 11 with bolts 19 and nuts 21. In FIG. 7,
Reference numeral 20 denotes a reinforcing plate.

[0004] In some cases, the seating surface of the seat cushion 1 is raised depending on the type of vehicle. In this case, the front and rear legs 8, 8 are usually mounted on a pedestal or the like. Further, a rear finisher is provided on the back side of the seat cushion 1.

[0005]

However, in order to mount the front and rear legs 8, 8 on a pedestal or the like when the seating surface of the seat cushion 1 is increased in a conventional vehicle seat,
It has the disadvantage that the number of parts increases and the weight also increases, and the appearance is deteriorated. Seat cushion 1
When the front and rear legs 8, 8 are formed to be long so that the seating surface of the front and rear slide members 3 is high, the rigidity is weakened, and there is a possibility that the lock mechanism of the front and rear slide mechanism 3 may be in a half-lock state. Furthermore,
When a rear finisher is provided on the back side of the seat cushion 1, the rear finisher does not have rigidity, and therefore, there is a risk that a rear seated passenger may be damaged by getting on and off.

An object of the present invention is to eliminate the need for placing the front and rear legs on a pedestal or the like when the seat cushion has a high seating surface, thereby reducing the number of parts and reducing the weight. Even if the front and rear legs are formed long so that the seating surface of the seat cushion becomes high, there is no risk that the rigidity will be weakened, and there is no risk that the locking mechanism of the front and rear slide mechanism will be in a half-locked state. It is an object of the present invention to provide a vehicle seat excellent in economical efficiency in which the rear finisher on the side is not likely to be damaged by a passenger sitting in and out of a rear seat, and the appearance is not deteriorated.
