[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat belt anchor device for a movable seat for an automobile.

[0002]

2. Description of the Related Art As shown in Japanese Utility Model Laid-Open Publication No. Sho 62-203767 or Japanese Utility Model Laid-Open Publication No. Sho 62-157660, a conventional seat belt anchor device for an automobile seat has one end of a webbing of a seat belt attached to a vehicle body. The seat is fixed and the other end is extended above the seat cushion through a gap between the seat cushion and the seat back of the seat.

[0003]

However, according to such a seat belt anchor device for an automobile seat, it is sufficient if the seat is fixed, but if the seat 1 is made movable as shown in FIG. Since the position of the seat belt webbing 2 does not change due to the anchor bolts 5 fixing the anchor plate 3 of the seat belt webbing 2 to the vehicle body 4 shown in FIG. Abdomen 7a of occupant 7 of seat 1
And the amount of movement of the seat 1 is naturally limited.

Therefore, in the present invention, there is provided a seat belt anchor device for a movable seat for an automobile in which a seat cushion of a seat belt webbing and a length extending from a seat back are the same regardless of the position of the seat. It is intended to provide.

[0005]

In order to achieve the above object, the present invention provides a seat belt anchor device for a movable seat for an automobile, which is rotatably supported on a vehicle body and constantly biased upward. A webbing guide rotatable downward by a sheet pressing means, and a rod fixed at a position close to a shaft support of the webbing guide and cross-linked between the free end portions of the webbing guide. And a seat belt webbing extending on the seat cushion from a gap between the seat cushion and the seat back of the seat, wherein a pressing means is disposed at a rear portion of the seat cushion and the webbing guide is provided. Is formed of a plate capable of pressing the free end downward.

[0006]

Therefore, when the seat cushion is moved forward, the webbing guide pushed downward by the pressing means is moved upward by the urging means, so that the amount of projection of the webbing extended from the rear portion of the seat cushion is secured. Is done. Next, when the seat cushion is moved backward, the webbing guide is moved downward by the pressing means, so that the webbing is wound up, and the amount of projection of the webbing extended from the rear portion of the seat cushion is determined by moving the seat cushion backward. Nevertheless, since the same amount of seat cushion as that at the front is secured, the above-mentioned conventional problem is solved.

[0007]

1 to 5 relate to an embodiment of the present invention, and the same members as those in FIGS. 6 to 8 are denoted by the same reference numerals, and redundant description will be omitted.

Reference numeral 10 is a seat belt anchor device for a movable seat for an automobile of the present invention. The seat belt anchor device 10 for a movable seat for an automobile is provided with respect to an anchor plate 11 fixed to the vehicle body 4 with anchor bolts 5. The pin 12 is rotatably supported by a pin 12 and is constantly urged upward by a winding spring 13 as urging means wound around the pin 12, and is turned downward by a pressing means 14 of the sheet 1. A possible webbing guide 15 is fixed to an anchor plate 11 at a position close to a pin 12 serving as a shaft support portion of the webbing guide 15 and between the free end portions 15a, 15a of the webbing guides 15, 15. Through the gap 17 between the seat cushion 1a and the seat back 1b of the seat 1 through the rod 16 cross-linked. Comprising a seat belt webbing 18 extending on down 1a. The pressing means 14 includes:
The free end portion 15a of the sheet is arranged in the rear 1a ₁ of the pipe frame 19 of the cushion 1a and the webbing guide 15, 15, 15a to a plate made of a pressable iron plate downward.

Therefore, as shown in FIG. 2, when the seat cushion 1a is moved forward, the free end portion 15a side of the webbing guide 15, which has been pushed downward by the pushing means 14, moves forward, so that the webbing guide 15 is not pushed. Since it is moved upward by the means 13, the rear portion 1a _{1 of the} seat cushion 1a is moved.
The projection amount a of the webbing 18 extended from the webbing is secured. Next, as shown in FIG. 1, when the seat cushion 1a is moved backward, the free end 15a side of the webbing guide 15 is moved downward by the pressing means 14, so that the webbing 18 is pushed down by the rod 16. Can be Therefore, only the depressed the minute, even though the rear 1a ₁ of the seat cushion 1a moves backward, the projecting amount a of the webbing 18 which extends from the rear 1a ₁ of the seat cushion 1a is the seat cushion 1a Is secured in the same amount as that at the front, so that the occupant 7 can always secure an appropriate belt tightening state. Reference numeral 20 denotes a buckle fixed to the free end of the webbing 18.

[0010]

[Effect of the invention] As described above, according to the invention,
As a seat belt anchor device for a movable seat for an automobile, a webbing guide rotatably supported by a vehicle body and constantly urged upward and rotatable downward by a sheet pressing means, Extending between the seat cushion and the seat back of the seat via a rod which is fixed at a position close to the shaft support portion and is bridged between the free ends of the webbing guides. And a pressing means is provided at a rear portion of the seat cushion and includes a plate capable of pressing a free end of the webbing guide downward. When the webbing guide is moved forward, the webbing guide pressed downward by the pressing means moves upward by the urging means. Thus, the amount of projection of the webbing extending from the rear portion of the seat cushion is secured, and when the seat cushion is moved backward, the webbing guide is moved downward by the pressing means, so that the webbing is wound up and the seat cushion is taken up. The amount of protrusion of the webbing extending from the rear of the seat cushion is the same as that of the front of the seat cushion despite the back of the seat cushion. The amount of protrusion of the belt webbing extending from the seat cushion and the seat back is the same, and there is a practical effect of providing a seat belt that does not tighten the belly of the occupant sitting on the seat cushion.
