Abstract

PROBLEM TO BE SOLVED: To provide an automobile rear seat having a reinforcement structure therefor to allow for the improvement of the rigidity of the automobile body in view of the situation of its guide rails in vehicles such as vans between the suspension towers on both sides in the width direction of the vehicle where a larger torsional load is applied. SOLUTION: A rear seat is mounted on guide rails 10 arranged on the floor between suspension towers 6 on both sides in the width direction of the vehicle so as to be slidable forward and backward. Both guide rails 10 are fixed through the floor to floor side members 2 on both sides in the width direction of the vehicle to which the floor is fixed, and a reinforcement frame 20 is arranged over between the guide rails 10 and is fixed thereto at its both end portions.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear seat of an automobile in which seats are guided by guide rails arranged on both sides of a floor so as to be slidable in the longitudinal direction of the vehicle.

[0002]

2. Description of the Related Art A rear seat slidable in the front-rear direction of an automobile generally has guide rails arranged on both sides in the vehicle width direction of a floor, and slidably guides a slide frame attached to a lower portion of a seating portion. I have. In order to smoothly perform such a rear seat sliding operation, it is necessary to consider the rigidity of the guide rail and the slide frame structure. However, the rigidity of the guide rail side is not increased by an additional structure. Was.

SUMMARY OF THE INVENTION The present invention focuses on the fact that in a van type vehicle or the like, such a guide rail is located between suspension towers on both sides in the vehicle width direction where a large torsional load is applied. It is another object of the present invention to provide a rear seat of an automobile having a reinforcement structure of the rear seat in consideration of improvement in rigidity of the automobile body.

[0004]

In order to achieve this object, the present invention provides a seat slide guide rail disposed on both sides of a floor between suspension towers in the vehicle width direction.
In a rear seat of an automobile in which a seating portion is slidably mounted in a vehicle front-rear direction, guide rails on both sides are fixed via a floor to floor side members on both sides in the vehicle width direction to which the floor is fixed. The reinforcing frame is bridged between the guide rails, and both ends thereof are fixed to the guide rails.

The reinforcing frame is bridged and fixed between the guide rails fixed to the floor side members, thereby suppressing deformation of the guide rails and increasing rigidity against a load applied to the guide rails from the seating portion. The floor side members to which a torsional load is applied from the suspension tower areas on both sides are reinforced via guide rails.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A sliding rear seat of a van-type automobile according to an embodiment of the present invention will be described with reference to FIGS. The seating portion 9 of the double-type rear seat, which is integrally slid in the vehicle front-rear direction on both sides in the vehicle width direction shown in FIG. 3, is mounted on the guide rails 10 on both sides in the vehicle width direction, and is provided below the seating portion 9. The slide frame is slidably guided and locked at an arbitrary slide position. These guide rails are arranged between the suspension towers 6 on the floor 1 welded to the floor side members 2 on both sides in the vehicle width direction. A spare tire storage 7 is formed on the floor 1 between them.

As shown in FIG. 2, a U-shaped rein hose 5 having a bolt insertion hole 5a provided with a weld nut (not shown) on the back surface thereof is provided on the floor side members 2 on both sides.
Are welded on both front and rear sides. In these rein hoses, lugs 11 projecting from the front and rear ends of the guide rail 10 and having bolt insertion holes 11a formed therein are screwed by bolts 16 through the bolt insertion holes 1a of the floor 1.

Reference numeral 20 denotes a reinforcing frame which is bridged between the guide rails 10 on both sides. The reinforcing frame 20 has an arc-shaped relief portion 23 corresponding to the spare tire storage portion 7, and has bolt insertion holes 21a for inserting the bolts 16 at four corners. Is formed. Corresponding to these screw seats, lugs 12 each having a bolt insertion hole 12 a having a weld nut formed on the back surface thereof are provided on the guide rail 10 so as to protrude toward the interior of the vehicle.

As a result, the reinforcing frame 20 is screwed to the lug 12 by passing the bolt 16 through the bolt insertion hole 21a, fixed in a bridge state between the guide rails 10, and deforming the gap between the guide rails 10 or between them. And also functions as a reinforcing member for the floor side member 2 to which a torsional load is applied from the region of the suspension tower 6 in particular. Therefore, it is also possible to fix the cross member between the floor side members 2 with a correspondingly reduced rigidity or to eliminate the cross member. Since the reinforcing frame 20 is in the form of a plate having an opening, the appearance is not impaired even when the seating portion 9 is largely slid forward to expose the floor 1 located below its normal position.

The reinforcing frame may be formed in a rectangular parallelepiped frame having a U-shaped cross section instead of the above-mentioned plate shape and welded to the guide rails on both sides. Further, the present invention has a structure in which the seat is not merely a sliding type, and the seating portion is raised upward in a state where the backrest portion is tilted forward in order to increase the storage space for luggage after sliding forward. Also applicable to

[0011]

As described above, according to the present invention, by joining the guide rails separated on both sides in the vehicle width direction, it is possible to maintain the mounting accuracy between the guide rails and to ensure the smooth sliding of the seating portion. . By connecting the floor side members on both sides on the back side of the floor in the suspension tower area via the guide rails connected to these members, the rigidity of the body, particularly, the torsional rigidity is also improved. The floor side members can be eliminated or simplified.
