Abstract

PROBLEM TO BE SOLVED: To reduce weight without increasing a plate thickness of material to ensure strength, and prevent a submarine phenomenon which occurs in an occupant restricted by a seat belt at collision at front part. SOLUTION: In an approximately U-shaped strut pipe 16, ends 19, 19 of both pipes are supported to front ends of right and left movable rails 23, 23 of a seat track 20, respectively. A strut top 17 of the strut pipe 16 is put to a lower surface 13 of a front panel 12, whereby the strut pipe 16 is fixedly coupled to the front panel 12, and is arranged between the right and left movable rails 23, 23 and the seat cushion frame 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger car, a wagon,
Driver seats for recreational beagle, etc.
The present invention relates to a separate seat for an automobile, which is used as a passenger seat, a second seat, or the like.

[0002]

BACKGROUND ART Conventionally, in a car seat, a sturdy seat cushion frame has been adopted as a measure for preventing a submarine phenomenon that occurs in an occupant restrained by a seat belt during a frontal collision. Therefore, since a thick steel plate is used, it is difficult to reduce the weight of the seat cushion frame.

[0003]

An object of the present invention is to reduce the weight without increasing the plate thickness of the material to secure the strength, and to prevent the submarine phenomenon which occurs in the occupant restrained by the seat belt at the time of a frontal collision. The purpose is to provide separate seats for automobiles.

[0004]

[Means corresponding to the problem and its action]
A substantially U-shaped strut pipe is supported at its both pipe ends by the front ends of the left and right movable rails of the seat track,
Then, its strut top is attached to the lower surface of the front panel of the seat cushion frame and fixedly coupled to the front panel, and between the left and right movable rails and the seat cushion frame. In the event of a frontal collision, the strut pipe is also stretched against the input from the occupant to keep the front side of the seat cushion in a normal state.

DESCRIPTION OF SPECIFIC EXAMPLES Hereinafter, based on the specified and illustrated specific examples, in order to explain a separate seat of an automobile of the present invention, FIGS. 1 and 2 are utilized for a driver seat of a passenger car. 10 partially shows an embodiment 10 of the vehicle separate seat of the present invention, and the driver seat 10 includes a seat cushion, a seat
It is assembled from the back and the head restraint, and the seat track 20 is assembled to the seat cushion frame 11 of the seat cushion, and the seat track 20 is installed on the floor of the passenger car. The seat track 20 is composed of a slide mechanism 21 and a lock mechanism, and the slide mechanism 21 is fitted to the left and right fixed rails 22 and 22 and the left and right fixed rails 22 and 22 in a reciprocally movable manner. Since it is assembled with the left and right movable rails 23, 23, the seat cushion frame 11 is mounted on the left and right frame support brackets 1.
5, the front ends of the left and right frame sides 14, 14 are set to the front ends of the left and right movable rails 23, 23, and the rear ends of the left and right frame sides 14, 14 are set to the rear ends of the left and right movable rails 23, 23. Connect the sheet to each end
Incorporate the seat track 20 into the cushion.

In this driver seat 10, a substantially U-shaped strut pipe 16 has its both pipe ends 19 and 1.
9 is supported on the front ends of its left and right movable rails 23, 23 of its seat track 20, and its strut top 17 is attached to the underside 13 of the front panel 12 of its seat cushion frame 11. It is spot-welded to the front panel 12, and is mounted between the left and right movable rails 23, 23 and the seat cushion frame 11.

Specifically, the strut pipe 16
Is continuously bent from a slender pipe having a predetermined outer shape to its strut top 17 and left and right projecting struts 18 and 18, and is bent into a substantially trapezoidal shape. Strut column 18,
The lower end of 18 is crushed into a plate shape and fastened to the left and right movable rails 23, 23 together with the left and right frame support brackets 15, 15, and the strut
Top 16 is its underside 13 of its front panel 12
Attached to the front panel by spot welding 12
Fixedly connected to. There, the strut pipe 16 is appropriately tilted in a compression direction with respect to an input from an occupant restrained by a seat belt in a frontal collision, so that the seat cushion frame 11 and the seat track 20 are separated from each other. Be intervened.

In this driver sheet, 2
4 is a towel bar type operating lever of the lock mechanism, 25
Is a front floor bracket and 26 is a rivet.

Therefore, in this driver seat 10, when a frontal collision occurs, the input from the occupant restrained by the seat belt is received from the front panel 12 and the left and right frame sides 14, 14 of the strut pipe 16 thereof. , The left and right movable rails 23, 23, the left and right fixed rails 22, 22, and the front side of the seat cushion kept normal by being transmitted to the floor of the passenger car, and the submarine phenomenon occurring in the passenger. Is prevented in advance. Further, the front panel 12, the left and right frame sides 14, 14, and the left and right frame support brackets 15, 15 can be made thin and lightweight by the strut pipes 16, and the strength can be increased. In addition, the shape can be simplified and the cost can be reduced.

As is apparent from the specific embodiments of the present invention described above with reference to the drawings, those skilled in the art to which the present invention pertains have a general knowledge of the present invention. , The nature of the invention (nat
ure) and essence (substance),
Then, it is easily embodied in another mode that is objectively recognized when they are included. Of course, the content of this invention is
It corresponds to the subject of the invention (be commensura
te with), and is essential for the establishment of the invention.

Benefits of the Invention As can be seen from the above, the separate seat of the motor vehicle of the present invention comprises a substantially U-shaped strut
A pipe is supported by its two pipe ends on the front ends of the left and right movable rails of the seat track, and its strut tops are attached to the underside of the front panel of the seat cushion frame on its front panel. In the separate seat of the automobile of the present invention, the occupant restrained to the seat belt at the time of frontal collision is fixed because it is fixedly coupled and is interposed between the left and right movable rails and the seat cushion frame. Input from its front panel and its left and right frame sides to its strut pipes, and then its seat
Sequentially transmitted to the truck and then to the body floor, the front side of the seat cushion is kept in a state, and
The submarine phenomenon that occurs in the occupant is prevented in advance, and the front panel and the left and right frame sides are thinned by the strut pipes to reduce the weight, and the strength is secured. The shape can also be simplified and the cost reduced, so that it is very useful and practical for automobiles.
