Embodiment Construction

[0030] Embodiments for carrying out the present invention will be described below using the drawings.

[0031] figure 1 It is a figure which schematically shows the seat belt apparatus which is an example of embodiment provided with the seat belt retractor concerning this invention.

[0032] like figure 1 As shown, the safety belt device 1 of this example is basically the same as the conventionally known three-point safety belt device. In the figure, 1 is a seat belt device, 2 is a vehicle seat, 3 is a seat belt retractor located near the vehicle seat 2, 4 is wound on the seat belt retractor 4 in a pull-out manner and The seat belt anchor 4a at the front end is fixed to the floor of the vehicle body or the seat belt on the vehicle seat 2, and 5 is a guide for guiding the seat belt 4 pulled out from the seat belt retractor 3 to the occupant's shoulder direction. 6 is a tongue that is slidably supported on the safety belt 4 guided from the guide holder 5, and 7 is fixed on th...

Abstract

The present invention enables the pretensioner to operate more efficiently, and at the same time shortens the length of the guide tube as much as possible to effectively reduce the weight, and can restrain the restriction on the shape of the guide member, and manufacture the retractor more cheaply . A mounting portion (17c) formed of a convex portion is provided on one end portion (17a) of a conduit (17) for accommodating a plurality of balls as a force transmission member. Furthermore, a mounting groove (18a) formed of a concave portion is provided on a guide member (18) having a guide surface (18c) for guiding the balls. And, by fitting the mounting part (17c) into the mounting groove (18), the conduit (17) is mounted on the outer periphery of the guide member (18) mounted on the frame. The catheter (17) can be shortened by having the guide part (18) on the outer periphery of the catheter (17).

Description

technical field [0001] The present invention relates to the technical field of a seat belt retractor including a pretensioner and the technical field of a seat belt device for a vehicle. Background technique [0002] Conventionally, various seat belt retractors equipped with pretensioners have been developed as seat belt devices installed in vehicles such as automobiles. Regarding this type of pretensioner, in an emergency such as when a vehicle is collided with a deceleration greater than the normal deceleration, the reaction gas generated by the gas generator is initially used to make the reel of the seat belt retractor to the direction of rotation. The seat belt winding direction is rotated, and the seat belt is wound by the spool. As a result, the slack of the seat belt can be quickly eliminated and tension can be generated in the seat belt, so as to improve the restraint force on the occupant. [0003] As an example of a conventional pretensioner, there is known a pre...
