Embodiment Construction

Embodiments of an inflatable seat belt apparatus according to the present invention are now described referring to the attached drawings.

FIG. 3 is a simplified perspective view showing a whole structure of the inflatable seat belt apparatus 1. This figure illustrates .[.for clarifying relationships between.]. respective components of the inflatable seat belt apparatus applied to the right side front seat.

In this figure, numeral 2 designates a shoulder belt. The shoulder belt 2 has an end 2a to which a tongue 3 is fixed. The shoulder belt 2 is engaged and fixed to a buckle 4 fixed to a predetermined position near the floor between the right and left front seats via the tongue 3 and has the other end 2b downwardly guided through a slip guide 5 or a pillar anchor mounted on a pillar P. The pillar anchor is adjustable in upper and lower directions. The shoulder belt is thus hung around and from the slip guide 5 to be wound up in an ELR 6 arranged near the floor.

Abstract

An inflatable seat belt apparatus is formed of an inflatable portion which is usually maintained in a band shape and has an envelope part inflated and deployed in a spindle shape by introducing gas generated by a gas generating device, the gas generating device acting in case of exceeding a predetermined threshold, a webbing having the inflatable portion extending over at least a range directly contacting with an occupant, a tongue fixed to an end of the inflatable portion and having a gas path from the gas generating device and a buckle to which the tongue is detachably engaged. The inflatable portion has an elastic inflatable unit inserted into the envelope part and is inflated and deployed by introducing the gas generated by the gas generating device into the elastic inflatable unit via a filter.

Description

BACKGROUND OF THE INVENTIONThe present invention relates to an inflatable seat belt apparatus, more particularly to an inflatable seat belt wherein a webbing of a seat belt apparatus to restrain an occupant has an inflatable structural portion formed in an envelope shape which is usually maintained in a band shape and is inflated, in an accident in a predetermined form to withstand high temperature gas spouted from a gas generating means.Presently, a seat belt apparatus is necessary for a vehicle or the like as an apparatus for securing in occupant's body, which restrains the occupant from sudden movement by a deceleration and an impact in a crash.Such a seat belt apparatus comprises a webbing as a woven belt made of a fabric which has approximately a 50 mm width and is formed according to Japanese Industrial Standard, a retractor (hereinafter referred to ELR: Emergency Locking Retractor), a buckle, a tongue, an anchor and so on. The ELR winds the webbing by a winding force of a spr...
