Description

[Detailed explanation of the idea] The present invention relates to a seat belt structure for an automobile.

Conventionally, one end of an automobile seatbelt is not attached to the seat but to the floor of the vehicle body, so it gets in the way of the feet of rear seat occupants and is easily soiled by the shoes of rear seat occupants. There is.

The present invention was proposed in view of these circumstances, and aims to provide a lightweight and inexpensive automobile seatbelt structure that does not interfere with rear seat passengers. An inverted U-shaped leg pipe frame with a horizontal portion extending in the width direction of the vehicle, a seat cushion assembly whose rear end is supported on the leg pipe frame, and a seat cushion assembly supported at the rear end of the seat cushion assembly. and a seat back assembly extending upwardly, the seat cushion frame being disposed at the rear end of the seat cushion assembly and extending substantially parallel to the rear and above the horizontal portion of the leg pipe frame; a belt anchor reinforcement having a flat surface and fixed to the horizontal part of the leg pipe frame so as to protrude upward; fixed to a lower end of the seat belt extending between the seat back assembly and the seat cushion assembly; The belt anchor plate is also provided with a belt anchor plate fixed to the rear end of the belt anchor reinforcement and protruding upward from the upper end of the belt anchor reinforcement.

An embodiment of the present invention will be explained with reference to the drawings.
Figure 1 is a perspective view showing the back of the seat, Figure 2 is a cross-sectional view of the seat belt attachment part in Figure 1, Figure 3 is a partially enlarged exploded view of Figure 2, and Figure 4 is a collision occurred in Figure 2. It is a sectional view showing the sheet at the time.

In the above figure, 1 is a seat assembly, 2 is a seat back assembly, 3 is a seat cushion assembly, 4 is a seat leg, 5 is a seat belt, and 6
1 is a box-shaped belt anchor reinforcement fixed to the leg pipe frame 7; 8 is a seat cushion frame; 9 is a seat back frame; 10 is a nut; 11 is a bolt; 12 is a belt anchor plate; It is fixed to belt anchor reinforcement 6.

In such a structure, the belt anchor plate 12 of the seat belt 5 is fixed to the belt anchor reinforcement 6 welded to the leg pipe frame 7 of the seat leg 4 with bolts 11 and nuts 10, so that the belt anchor plate 12 of the seat belt 5 is fixed to the belt anchor reinforcement 6 welded to the leg pipe frame 7 of the seat leg 4 with bolts 11 and nuts 10. Since there is no structural member connecting the leg pipe frame 7 and the seat cushion frame 8, the seat belt 5
wraps around the rear part of the cushion and extends from between the cushions to the surface of the cushion.

The upper surface of the belt anchor reinforcement 6 forms a horizontal shelf, and the upper end of the belt anchor plate 12 projects above the flat shelf by a height h. The height h is such that the upper end of the belt anchor plate 12 comes almost to the upper end of the seat cushion frame 8 when the seat cushion frame 8 is deformed and comes into contact with the upper surface of the belt anchor reinforcement 6.

Therefore, for example, when a car crashes, the seatbelt 5 is tightened when the occupant moves forward due to the impact.
When a load is applied to the
The seat belt 5 with the seat cushion wrapped around it presses the seat cushion and the seat cushion frame 8 downward, and the anchor reinforcement 6
The seat cushion frame 8 that is brought into contact with the upper surface and pushed in strongly contacts the protrusion of the belt anchor plate 12, behaves in the same way as the leg pipe frame 7 to which the seat belt 5 is attached, and acts as a strength member. act.

According to such a structure, although it is a simple structure in which the belt anchor plate 12 is simply attached to the leg pipe frame 7, the upper end of the belt anchor reinforcement 6 is a flat surface, and the belt anchor plate 12 does not move upward from the flat surface. Since it protrudes, it is possible to obtain the same strength as a combination of the leg pipe frame 7 and the seat cushion frame 8 in the event of a collision.

In short, according to the present invention, there is provided an inverted U-shaped leg pipe frame that protrudes above the vehicle interior floor and whose horizontal portion extends in the vehicle width direction, and a seat cushion whose rear end is supported on the leg pipe frame. assembly and
and a seat back assembly supported by the rear end of the seat cushion assembly and extending upward, the seat back assembly being disposed at the rear end of the seat cushion assembly and above and rearward of the horizontal portion of the leg pipe frame. a seat cushion frame extending substantially parallel to the seat cushion frame; a belt anchor reinforcement having a flat surface at its upper end and fixed to the horizontal portion of the leg pipe frame so as to protrude upward; and between the seat bag assembly and the seat cushion assembly; The belt anchor plate is fixed to the lower end of the seat belt extending through the seat belt, is fixed to the rear end of the belt anchor reinforcement, and protrudes upward from the upper end of the belt anchor reinforcement. The present invention is industrially extremely useful because it provides an automobile seat belt structure that does not interfere with occupants.
