Description

[Detailed Description of the Invention] This invention has a seat belt whose tip end is attached to a door or body of a car, whose other end is fixed to a floor tunnel side, and which is connected to a tractor, and which changes direction on a seat cushion. This relates to a seat belt through which is provided on the seat so that it does not come into contact with the seat belt.

BACKGROUND ART Conventionally, there are seat belt through belts for automobiles of this type as shown in FIGS. 1 and 2.

In the figure, reference numeral 1 denotes a seat, which is made up of a seat cushion 1m that is attached to the floor of the vehicle body and can slide freely, and a seat pack 1b that is connected to a seat cushion sheet 1.

A door 2 is provided near one side of the seat for passengers to get on and off the vehicle. The door 2 is provided with a window 2b and a window frame.

On the other hand, the seat tail is connected to the buckle 4 attached to the window frame of the seat coil 2 which is fixed to the central tunnel part of the seat 1 and pulled out from the retractor 6. The belt through 5 has the long axis of the annular part vertical so that the shield belt 13 is inserted therethrough and stands upright on the side of the seat cooker 1& of the seat l, and has a slope 4 so that the shield belt 3 can be easily pulled out. It is installed in parallel.

However, as shown in FIG. 2, such a conventional seat belt through 5
Since the vertical annular body is fixed to the side surface of the seat cushion 1a in an upright state and slightly protrudes above the circumferential upper edge of the seat cushion 1a, when the door 2 is opened or closed, the seat belt 3 is attached to the seat cushion 1a. seat cushion 1
1 may come into contact with the upper edge of the circumferential side (P). Therefore, when the seatbelt through 5 is attached to one side of the seat cushion 1a, the height and inclination angle of the mounting position must be adjusted, and the seat belt through 5 must be adjusted to the seat cook 1 to avoid contact. When installed protruding from the top surface of 1 meter, there were problems in that it got in the way when shifting or moving to the next seat, and the appearance was poor.

This invention was made by paying attention to such conventional problems, and it is possible to eliminate the seat belt through which is attached to the side of the seat.

By forming an approximately two-shape or an S-shape with an inclined sliding part that changes direction and a horizontal sliding part that guides the seatbelt whose direction has been changed by the inclined sliding part to the gutter or single body side. , aims to solve the above problems.

The present invention will be explained below based on the drawings. Figures 3 to 6
The figure shows a first embodiment of the invention. First, to explain the configuration, in the figure, reference numeral 21 is a seat held through, and the outline of the seat belt through 4 is that the shoulder belt 3 is hung by an inclined sliding part 21b that changes the passing direction, and a tilted sliding part 21b that changes the direction. It is formed of a horizontal sliding part Δ that guides and slides the shield belt 3, and a mounting part n that is attached to one side of the seat cushion 11 of the seat l. The horizontal sliding portion 21m and the inclined sliding portion in this embodiment are formed by bending a continuous steel bar on the same plane. More specifically, the horizontal sliding portion 21m is spaced apart from and approximately parallel to the upper circumferential edge of the seat cushion 1a of the seat l, and is set at a position slightly protruding from the upper surface of the seat cushion 1a, and the tip thereof is It is formed by folding back to a position about a hand's length away. The inclined sliding part 21b is formed by extending from the horizontal sliding part 211 and being bent downward.

The mounting portion 21C is formed to further extend from the inclined sliding portion 21b. Therefore, the seat pelt room has a substantially double-shaped shape, and is attached to one side of the seat cushion la of the seat 1 by a fixing member n. A seatbelt 3 pulled out from the tractor 6 located on the right side as shown in Fig. 3 is passed through the seatbelt through 4. The buckle belt 3, which is passed over the moving part 21b, is connected to the tank 71 at its tip, as shown in FIG. 1, to the buckle 4 attached to the window frame.
is installed on.

Next, the effect will be explained.

To insert the shield belt 3 through the seat belt through 21, pull out the shield belt 3 from the retractor 6, pass it through the inclined sliding part 21b of the seat belt room, and pass the shield belt through the seat belt 3. The drawing direction is changed and the paper is inserted between the horizontal sliding part 21 and its folded part and drawn out. The pulled-out shoulder belt 3 is used to hang the upper body of the occupant, and the tongue 7 at the tip of the shoulder belt 3 is attached to the buckle 4 attached to the window frame 2a of the door 2. Therefore, you can get on and off the vehicle without having to remove the tongue 7t each time you open or close the door. At this time, the horizontal sliding part 21m of the seat pelt room protrudes slightly from the surface of the 7-touch seal 1a of the seat 1, and is spaced apart from the upper edge of the circumferential side of the seat cushion 1a, and is set almost parallel to the surface. Therefore, the pulled out shoulder belt 3 faces the side surface of the seat portion 1a. Therefore, when a passenger gets on or off the vehicle, the seat belt 3 may be pulled when the door 2 is opened with the seat belt 3 attached to the door 2, or the seat 1 may slide back and forth, causing the seat belt 3 to tighten. Even if it is pulled, the upper edge of the circumferential side of the seat cushion laO of the seat 1 does not come into contact with the shield belt 3, so there is no risk of damaging the seat cushion 1m.
