JPS5822743A - Binding device in seat for automobile - Google Patents

Abstract

PURPOSE:To eliminate the occurrence of an inconvenience in the binding property of a seat belt for an occupant sitting on a seat even if a seat position is slid by mounting a belt retractor and a belt guide at the cushion frame of a seat for an automobile. CONSTITUTION:A belt retractor 6 is mounted at one side of a cushion frame 8, and a belt guide 7 is mounted at the other. A belt 5 is led from the hole 12 of a cushion frame 8 at the other side. Since the retractor 6 is mounted on the frame 8, the relative position relationship between the seat belt and an occupant sitting on the seat does not alter, even if the seat is longitudinally moved, and no defect occurs in the restricting property of the belt. Since the retractor 6 and the guide 7 are disposed at both sides of the frame, the frame 8 itself can be reduced in weight.

Description

[Detailed description of the invention] The present invention relates to a restraint device for a seat in a vehicle or the like.

In a vehicle seat, a seated person is restrained by a seat belt to prevent the seated person from flying out when receiving an impact such as a collision. When the seat belt is not in use, such as when the occupant is not seated, it is rolled up and stored inside the belt retractor so that it is not exposed above the seat, and when the seated person retracts the seat belt, it is pulled out from the belt retractor. I am wearing it.

Conventionally, the bell) IJ) rafter of this type of restraint system was attached to the vehicle body, so when the occupant moves the car seat position and sets it to the desired position, the relative positional relationship of the seat belt to the occupant changes. In addition to causing problems in restraint performance, the total length of the seatbelt led out from the belt retractor becomes longer, which causes the seatbelt itself to stretch, resulting in a decrease in the restraint performance of the seated person in the event of a collision or the like.

The present invention has been made in view of the above problems, and in order to improve the restraint of the seat belt on the seated person, a belt retractor is incorporated into the cushion frame of the seat, and the tension of the seat belt against the cushion frame is efficiently pulled. The purpose of the present invention is to provide a restraining device that is designed to increase the amount of movement of the cushion frame itself.

The present invention will be described in detail below regarding color correction.

In Figure 1, (1) shows the entire vehicle seat, and (2)
) is the seat pack, (3) is the seat cushion, and the seat adjuster slide rail (4) is installed on the bottom side. This seat cushion + 31K seat belt (

) is installed.

This restraint device will be explained in detail with reference to FIGS. 2 to 4.

The seat belt (5) stored in the cushion frame (8) is led out from a guide hole f121 formed in the side surface of the other side (8b) of the cushion frame (8).

The belt guide (7) has an inverted C-shape and its rear half is close to the rear part of the other side (sb) of the cushion frame (8), that is, the rear assembly part b' of the other movable side rail (9b). Then, fix it with POL) 03 and insert the tip into the guide hole 0z.
The seatbelt (51) is positioned diagonally upward on the rear side, and is guided through the guide hole α2 through the guide ring (7a) fixed to the tip of the seatbelt (51). This constitutes a restraint device.

In the figure, (9m') (9b') is the fixed side rail of the slide and idle rail (4), and α4 is the cushion frame (8).

As described above, according to the present invention, the belt retractor is disposed inside the seat cushion, and is installed at the front assembly position of the cushion frame and the seat adjuster slide rail integrally with the assembly, and at the rear assembly position. Attach a belt guide nearby and guide the seat belt stored in the belt retractor from the side of the cushion frame.
Since the seat belt is inserted through the belt guide and folded back to the upper front part of the seat cushion to be guided out, even if the seat position is moved, the relative positional relationship of the seat belt to the seated person does not change, which prevents problems in restraint performance. Moreover, the total length of the seat belt that is led out from the belt retractor is shorter than when the belt retractor is attached to a single unit as in the past, so the elongation of the seat belt itself is reduced, and the tension applied to the seat belt is reduced. is a belt retractor
Since the belt guide and the belt guide lIK are dispersed, the seated person can be stably supported and the seated person can be reliably restrained, improving safety in the event of a collision, etc.

In addition, since the belt retractor and belt guide are installed at the part where the cushion frame and slide rail are assembled, the tension of the seat belt is applied to this assembly part, and this tension is transferred between the cushion frame and the slide rail. kJ) Since the cushion frame receives the noise integrally, there is less N noise to the cushion frame, which reduces the strength of the frame and makes it lighter.Furthermore, the belt retractor is placed below the front of the seat cushion. This has great practical effects, such as not reducing the comfort of sitting.

Claims (1)

[Claims] In a vehicle seat where a seat adjuster is assembled to a cushion frame as a slide rail, a belt retractor is integrally attached to the front assembly position of the seven cushion frames and the slide rail, and a belt retractor is integrally attached to the rear assembly position. A belt guide is attached nearby, and the seat belt stored in the belt retractor is led out from the side of the cushion frame, and is inserted through the belt guide, turned around, and led out to the front of the seat.
