Description

[Detailed Description of the Invention] The present invention relates to a seat belt attachment device for a seat in a vehicle such as a bus.

In vehicles such as buses, a two-person seat is usually used as shown in Figure 1, and seat belts for such a two-person seat are attached to each backrest 1 as shown in Figure 2. and seat bells 3a, 3b and 4 via anchor plates 5 as shown in FIG.
Usually, a measure is taken to secure parts a and 4 b with bolts.

Then, 3a and 3b, 4a and 4b are connected to each other by buckles and locking devices such as tanks provided at their tips, so that the waist of a seated occupant is restrained.

(For example, see Japanese Utility Model Application Publication No. 53-11127.) In the conventional seat belt installation structure as described above, each of the four belts must be separately fixed to each backrest frame via an anchor plate with bolts. This is often inconvenient, as the number of installation steps increases, and four anchor plates are required for each two-person seat.

In the present invention, the central belts of the two sets of seat belts are attached adjacent to each other, and the adjacent parts of the backrests 1 and 2 are attached as shown in FIG. Brackets 6 that rotatably support the
Focusing on the fact that The number of parts has been significantly reduced.

The present invention will be explained below with reference to the embodiments shown in FIGS. 4 to 7.

As shown in Fig. 4, the two-person vehicle seat has backrests 1 and 2 pivoted on the outside to a side frame 7, which is a fixed member, and the center side of each backrest to a fixed member such as a cross pipe 8. Each of the backrests is pivoted to a center bracket 6 fixed to the member so that they can rotate independently, and the inclination angle of the backrest can be freely changed by operating an operating device (not shown). It has become.

This invention utilizes the above configuration and uses the central seatbelt) 3
b and 4b are constituted by one belt, and locking tools are provided at both ends of the one belt to respectively engage the locking tools provided at the tips of the other bevel leaves 3a and 4a, and as shown in FIG. As shown, the central part of the one belt is sewn to form an annular attachment part 9, and the center bracket 6 is provided with an insertion hole for a pin 10, and the pin 10 is inserted into the annular attachment part 9. By inserting and supporting both ends of the pin 10 into the insertion hole of the center bracket 6 in this state, both bells 3b and 4b can be attached at the same time.

The bells) 3a and 4a on both sides are attached to the side frame 7 via a tongue 11 as shown in FIG. It can be a lap belt.

The bells t-33 and 4a on both sides are attached to backrests 1 and 2.
It can also be attached to the outside of the frame la, 2a (see Fig. 2) and used in combination with the center side belts 3b, 4b to form a shoulder belt that fits from one shoulder to the other waist of the occupant. .

As described above, according to the present invention, the two-person seat is constructed by constructing the center side belt of each of the two sets of left and right seat belts with one belt, and attaching the center part of the belt to the center side of the backrest through the pin. By inserting and supporting the belt into the center bracket that supports it, it is possible to significantly reduce the man-hours for processing and installing the belt, and also to reduce the number of parts for installation, resulting in cost reduction. Together with the benefits obtained, the practical effects are extremely large.
