Abstract

An upper-front of a seatback is cut, providing a hole at a position the occupant's shoulder may lie, and an engaging means able to engage with a shoulder webbing is fitted in the hole. The engaging means holds the shoulder webbing, which is wrapped around the occupant. The engaging means is, for example, a (second) buckle fitted in the hole. A second tongue (intermediate tongue) is mounted on a middle part of the shoulder webbing. The shoulder webbing is wrapped slantwise around the occupant's shoulder when the second tongue is engaged with the second buckle.

First claim

What is claimed is:

1. A seat belt device for vehicle seats, comprising a webbing having a tongue and extending from a webbing feed port made in a pillar, when the tongue is inserted into a buckle provided on one side of a seat cushion, the upper half of the webbing used as a shoulder webbing is wrapped slantwise around the shoulder of the occupant sitting on the vehicle seat, and the lower half of the webbing used as a wrap webbing is wrapped around the hips of the occupant, thereby holding the occupant to the vehicle seat, wherein further comprising:
a hole provided by cutting the seatback at an upper-front part and located at a position where the shoulder of the occupant lies; and
a striker shaped as a cantilever provided in the hole and having a free end at an inner end, and the shoulder webbing is bent back, forming a bent part at the intermediated part and is substantially U-shaped, and is wrapped slantwise around the shoulder of the occupant, at the bent part engaged with the striker.

2. The seat belt device according to claim 1 , wherein the striker is secured to one side frame of a seatback frame.

3. The seat belt device according to claim 1 , wherein a gate-shaped striker and a latch are provided between the seatback and the pillar,
the latch is structured to engage with the gate-shaped striker, and
the gate-shaped striker and the latch are structured to hold the seatback at a standing position while the latch remains engaged with the gate-shaped striker;
the striker shaped as a cantilever is connected to the gate-shaped striker or the latch and has the free end extending along a centerline of the seat.

4. The seat belt device according to claim 1 , wherein the striker shaped as a cantilever is bent twice at middle part, forming a stepped part which prevents the shoulder webbing from slipping sideways.

5. The seat belt device according to claim 1 , wherein the free end of the striker shaped as a cantilever is bent, preventing the shoulder webbing from slipping sideways.

6. The seat belt device according to claim 2 , wherein a gate-shaped striker and a latch are provided between the seatback and the pillar:
the is latch structured to engage with the gate-shaped striker, and
the gate-shaped striker and the latch are structured to hold the seatback at a standing position while the latch remains engaged with the gate-shaped striker;
the striker shaped as a cantilever is connected to the gate-shaped striker or the latch and has the free end extending along a centerline of the seat.

7. The seat belt device according to claim 2 , wherein the striker shaped as a cantilever is bent twice at middle part, forming a stepped part which prevents the shoulder webbing from slipping sideways.

8. The seat belt device according to claim 2 , wherein the free end of the striker shaped as a cantilever is bent, preventing the shoulder webbing from slipping sideways.

9. The seat belt device according to claim 3 , wherein the gate-shaped striker or the latch, provided on the seatback, is connected to one side frame of the seatback frame.

10. The seat belt device according to claim 3 , wherein the striker shaped as a cantilever is bent twice at middle part, forming a stepped part which prevents the shoulder webbing from slipping sideways.

11. The seat belt device according to claim 3 , wherein the free end of the striker shaped as a cantilever is bent, preventing the shoulder webbing from slipping sideways.

12. The seat belt device according to claim 6 , wherein the gate-shaped striker or the latch, provided on the seatback, is connected to one side frame of the seatback frame.

13. The seat belt device according to claim 6 , wherein the striker shaped as a cantilever is bent twice at middle part, forming a stepped part which prevents the shoulder webbing from slipping sideways.

14. The seat belt device according to claim 6 , wherein the free end of the striker shaped as a cantilever is bent, preventing the shoulder webbing from slipping sideways.
