Embodiment Construction

[0026] Hereinafter, the best mode for carrying out the present invention will be described using the drawings.

[0027] figure 1 One embodiment of the seat belt device of the present invention is schematically shown, (a) is a view explaining the state when the pretensioner of the seat belt retractor operates, and (b) is explaining the pretensioning of the lumbar fixing part The view of the state when the tensioner is in action, and the same reference numerals are used to indicate the same as Figure 9 with Figure 10 The shown conventional seat belt device 1 has the same constituent elements, and detailed description thereof will be omitted.

[0028] Such as figure 1 As shown in (a), the seat belt device 1 of this example is the same as the above-mentioned conventional general three-point seat belt device. It is fixed on the vehicle body, and the other end side of the seat belt 4 is pulled out and wound around the seat fixed on the lower part of the vehicle body under the...

Abstract

Provided is a seat belt device, which can reliably eliminate slack of the lap belt and obtain a sufficient restraining effect on the occupant even if the two pretensioners operate in two stages. First, actuate the pretensioner (9) of the seat belt retractor (3), while pulling the shoulder belt ( 4b) and the lap belt (4c). Then, the pretensioner (10) of the lumbar fixing part (4a) is actuated, and the seat belt (4) is stretched to the side of the lumbar fixing part (4a), and the one-way tongue (5) is applied to the seat belt (4). 4) Clamp and lock it. Thereby, the shoulder belt (4b) cannot be moved to the lap belt (4c) side by the tongue piece (5). Therefore, the slack of the lap belt (4c) can be reliably eliminated, and the waist of the occupant can be firmly restrained.

Description

technical field [0001] The invention relates to a seat safety belt device which is assembled on a vehicle such as a motor vehicle and restrains and protects occupants by the seat safety belt, and relates to the technical field of the seat safety belt device including two pretensioners. Background technique [0002] Conventionally, seat belt devices installed on vehicles such as motor vehicles have restrained the occupant by the seat belt to prevent the occupant from Fly out from the seat to protect the occupant. [0003] As one of such conventional seat belt devices, for example, there is Figure 9 The three-point seat belt assembly shown. In the drawings, 1 denotes a seat belt device provided on a vehicle seat 2 . 3 denotes a seat belt retractor, which is fixed on the vehicle body near the vehicle seat 2, and always exerts force on the seat belt 4, so as to wind the seat belt 4 in a pull-out manner, in case of emergency The seat belt 4 cannot be pulled out. 5 denotes a t...
