Problems solved by technology

[0005] In addition to the above-mentioned conventional examples, it is also considered to provide a pretensioner for increasing the tension of the waist restraint webbing during a collision, but when the pretensioner is activated by the gas pressure from the gas supply source, it is necessary If you want to install the gas supply source for the pretensioner and the gas supply source for the chest inflation part separately on the vehicle seat, it is necessary to increase the loading space of the gas supply source, especially when you want to install it on the side of the seat. Ensure sufficient loading space

Embodiment Construction

[0027] Hereinafter, embodiments of the present invention will be described based on the drawings. In FIG. 1, the air belt device 10 for a vehicle of this embodiment is an air belt that restrains an occupant 14 seated on a vehicle seat 12, and includes a chest restraint webbing 16, a waist restraint webbing 18, The pre-tensioning device 20, the gas supply source 22 and the gas supply path 24.

[0028] The vehicle seat 12 includes: a seat cushion 25 with a seat frame 32 on which the occupant 14 is seated; a seat back 26 supporting the back of the occupant 14; and a headrest 28 provided on the upper portion of the seat back 26, It is slidably mounted on the seat rail 33 provided on the front panel 30 in the vehicle front and rear direction. A retractor 34 is pivotally mounted on the vehicle exterior side of the seat frame 32 to be swingable in the front and rear directions of the vehicle, and a buckle device 36 is pivotally mounted on the vehicle interior side of the seat frame 32 to...

Abstract

In order to enable a gas-supplying source (22) for operating a chest portion expansion portion (46) and a pretensioner (20) to be mounted on a limited mounting space in a motor vehicle seat (12) by commoditizing the gas supplying source (22), an air belt apparatus (10) for use in a motor vehicle includes chest-restraint webbing (16) having a chest expanding portion (46) corresponding to a chest portion (14B) of an occupant (14) at expansion, lumbar-restraint webbing (18) being pulled out from a retractor (34), and corresponding to a lumbar portion (14W) of the occupant (14), and a single gas-supplying source (22). Since the gas-supplying source (22) that supplies gas to the chest expanding portion (46) and a pretensioner (20) at a motor vehicle collision is unified and commoditized, the gas supplying source (22) can be mounted on a limited mounting space in a motor vehicle seat (12).

Description

Technical field [0001] The invention relates to an air safety belt device for a vehicle in which a chest expansion part is provided on a chest restraint webbing. Background technique [0002] An air belt device is disclosed in which the tension generated in the shoulder belt (breast restraint webbing) when the shoulder belt is expanded is also transmitted to the waist belt (waist restraint webbing) (see Patent Document 1 and Patent Document 2). [0003] Patent Document 1: JP 2000-255358 No. [0004] Patent Document 2: JP 2001-294111 A [0005] In addition to the above-mentioned conventional example, it is also considered to install a pre-tensioning device for increasing the tension of the waist restraining webbing during a collision. However, when the pre-tensioning device is operated by gas pressure from a gas supply source, it is necessary If you want to install the gas supply source for the pre-tensioning device and the gas supply source for the chest expansion part separately...
