Abstract

PURPOSE:To enable to easily fasten a seat belt by a method wherein the lower fixing part of a three point monuting type seat belt is automatically shifted back and forth along a horizontal straight guide member arranged in the neighborhood of a compartment interior side sill at the lower edge side of a door opening. CONSTITUTION:When the seating of a passenger is detected by a switch internally equipped at a seat cushion 26a and, after that, the closing of a door 4 is detected by a door switch, a motor 22 is rotated clockwise in order to shift the anchor 13 of the lower fixing part of the belt forward along the guide 16 to the rear part of the seat cushion 26a and to stop the anchor 13 there. In such a manner, the anchor 13 of the lower fixing part of the seat belt 10 only faces against the compartment interior side, while being brought into closely contact with the compartment interior side. Accordingly, the belt 10 slantwise faces against the opening 3, resulting in enabling to directly grasp the belt and to easily fasten the belt.

び肩に装着されることとなる。The three-point seat belt is as shown in FIG.
The seat belt 53 has one end disposed below the side or connected to the tractor 54, is folded back through a through ring 55 disposed above the side, hangs downward, and is fixed via an anchor 56 below the side. However, the belt 53 has a through ring 5.
A retaining tank plate 57 is slidably provided under the tank plate 5. When the seat belt 53 is not fastened, the door 5 is closed as shown in the figure.
The tank plate 57 is held vertically on the rear inside of the seat 58, and when it is installed, reach backwards, pinch the belt at the appropriate place, pull it forward and inward, and engage the tank plate 57 with a locking device such as a buckle located on the center side of the passenger compartment of the seat 58. In this way, the seat belt 53 is worn around the waist and shoulders.

以上の三点式シートベルトにおいて、シートベルトはシ
ートの後方の側方に位置するため、ベルトを装着しよう
とする場合、ベルトとの間に距離があり、ために身体を
捻って手を伸ばしてベルトをつかむ必要があり、装着操
作に不便である。In the three-point seat belts mentioned above, the seat belt is located at the rear and side of the seat, so when you try to put on the belt, there is a distance between you and the belt, so you have to twist your body and reach out to pull the belt. It is inconvenient to put it on because it needs to be grabbed.

特に２ドア車の如くドアが大きい場合にはシートベルト
を縦設するドア後方のピラ一部がシートの後方に離れ、
ベルトとの間の距離が大きくなり、装着操作が不便であ
る。Especially when the doors are large, such as in a two-door car, the pillar at the rear of the door where the seat belt is installed vertically moves away from the rear of the seat.
The distance between the belt and the belt becomes large, making it inconvenient to wear.

そこで上記シートベルトを前方に配設することも考えら

不便である。Therefore, it is conceivable to arrange the seat belt at the front, but this is inconvenient for passengers in the rear seats to get on and off the vehicle and for loading and unloading luggage.

あり、操作が面倒である。Various improvements have been proposed in the past in order to improve the above-mentioned problems. For example, in Utility Model Application No. 121020/1983, the belt guide arm l is raised diagonally to face the side of the seat in conjunction with the raising and lowering of the seat. It is pulled out to the side, and the belt guide arm is folded sideways and stored vertically behind the door, but according to this, when it is installed, the belt guide arm stands diagonally to the side of the seat and protrudes into the interior. It is hard to say that it is the best in terms of appearance. Matami Kai 53rd year
- In No. 36239, the sides of the roof section are moved forward and backward in conjunction with the seat belt folding and folding of the seat, but when the seat is folded down, the belt is vertically located in the middle or front of the door opening. It is difficult to say that it is the best for getting on and off the train and loading and unloading luggage. Furthermore, in Utility Model Application Publication No. 53-56624, a seatbelt locking hook is provided on the shoulder of the seatback, and the belt is locked to this so that when the seatback is worn, the user can reach out and grab the belt. However, in this case, in a two-door car, the seat back is folded down when the rear seat passenger gets in and out, and the belt needs to be attached and detached each time, making the operation cumbersome.

供するにある。The present invention has been made to overcome the above-mentioned disadvantages of the conventional three-point seat belt and the disadvantages of the above-mentioned conventional solutions that have been improved. A guide member is provided in the front-rear direction, and the lower end of the seatbelt that is folded back through the through ring and extended downward is attached and supported.When the seatbelt is worn, the guide member guides the lower end of the belt to the rear of the seat. The lower end of the seatbelt can be moved forward so that it faces the rear of the seat when it is not worn. The object of the present invention is to provide a three-point seat belt device for a vehicle, which has advantages such as not protruding.

。An example of a specific structure of the storage gap 333 is as shown in FIGS. 7 and 8. A part of the pillar on the rear seat window side is made up of a joined body of inner and outer plates 315 & 315b as shown in Fig. 7, and a lining member 315cL is provided inside the inner plate 315a so as to open forward, and the member 315 is closed at the rear end. There is. This formed the upper part 333aY of the gap. The front part of the lining member is thick under the part of the pillar, and this thick front part 315
d, from front to back, the four parts 315 are larger than the width of the belt.
