Benefits of technology

[0027]Since the engaging means is fitted in the hole located at the occupant's shoulder, a gap is scarcely provided between the shoulder webbing and the occupant's shoulder and seatback. The shoulder webbing can therefore be tightened in emergency, and can hold even an occupant of small physique to the vehicle seat, preventing the submarine phenomenon.
[0028]Further, it suffices to provide a hole in the upper-front part

Problems solved by technology

Moreover, since the engaging means lies within the hole made in the upper-front part of the seatback, it n

Example

Embodiment 2

[0066]Embodiment 2 shown in FIGS. 2A to 2C will be described. The components identical to those of the embodiment described above (Embodiment 1) are designated by the same reference numbers, and will not be described. The components distinguishing Embodiment 2 form Embodiment 1 will be described in the main.

Example

[0067]Embodiment 2 differs from Embodiment 1 in that a striker is embedded in the hole 20, not the buckle 18e2 as in Embodiment 1.

[0068]In Embodiment 2, the striker 32 is shaped like a cantilever, and its inner end (close to the vertical centerline of the seat) is the free end. The striker 32 shaped like a cantilever extends in the hole in the left-right direction from, for example, the outer side 20S (pillar-side) of the hole. The distal end (inner end) of the striker is a free end, and spaced from the inner side 20S′ of the hole. A part of the striker, for example the middle part 32b, is bent twice, forming a stepped part. In FIGS. 2B and 2C, the hole 20 is shown as a bottomed hole. However, in Embodiment 2, the hole 20 is not limited to a bottomed hole and a through hole may be used as the hole.

[0069]The shoulder webbing 18c is bent back at the intermediate part, and is substantially U-shaped. The part of the shoulder webbing, so bent back, is engaged with the striker 32 provided...

Example

Embodiment 3

[0089]FIGS. 6A to 6C show Embodiment 3 of this invention. The components identical to those of the embodiments described above (Embodiments 1 and 2) are designated by the same reference numbers, and will not be described. The components distinguishing Embodiment 3 from Embodiments 1 and 2 will be described in the main.

[0090]In Embodiments 1 and 2, a hole is made by cutting an upper-front part of the seatback. In Embodiment 3, a hole is made by cutting through an upper-front part of the seatback. Further, in Embodiment 1 the engaging means is the second buckle located in the hole (bottomed hole or through hole), and in Embodiment 2 the striker located in the hole (through hole or bottomed hole). In Embodiment 3, the engaging means is the striker arranged at the back of the hole (through hole). Embodiment 3 differs in these respects from Embodiments 1 and 2.

[0091]In Embodiment 3, a hole (through hole) 120 is cut through the upper-front part 16F of the seatback and may be...

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.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present invention claims priority under 35 U.S.C. §119 to Japanese Application No. 2014-114543, filed Jun. 03, 2014, the entire content of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to a seat belt device for the vehicle seat, which is designed to hold an occupant to the vehicle seat.[0004]2. Description of the Related Art[0005]As a seat belt device for holding an occupant to a vehicle seat, the three-point holding seat belt is broadly used to hold the occupant to the vehicle seat, at three points, i.e., the left or right shoulder and the left and right hips.[0006]The three-point holding seat belt (or three-point seat belt) comprise webbing. The webbing is taken up as a pulling force is applied to it from the retractor incorporated in, for example, a chassis pillar. The webbing extends from the retractor, through the webbing feed port made in the pill...
