Embodiment Construction

[0041] Hereinafter, the form for implementing this invention is demonstrated using drawing.

[0042] figure 1 It is a diagram schematically showing a seat belt device including an example of an embodiment of a seat belt retractor according to the present invention.

[0043] Such as figure 1 As shown, the seat belt device of this example is basically the same as the conventionally known three-point seat belt device. In the figure, 1 denotes a seat belt device, 2 denotes a vehicle seat, 3 denotes a seat belt retractor arranged on the vehicle body near the vehicle seat 2, and 4 denotes a seat belt retractor retractable to be wound up on the seat. The belt holder 4a on the reel of the seat belt retractor 3 and the front end is fixed to the seat belt on the vehicle floor or the vehicle seat 2, and 5 indicates the seat belt that will be pulled out from the seat belt retractor 3. The belt guide anchor that guides the seat belt 4 to the shoulder of the occupant, 6 indicates the t...

Abstract

To enhance quietness more effectively and perform power transmission more stably. An annular internal gear member (24) is formed from an abnormal noise emission inhibiting material having a lower hardness than a metal. Also, a deformation inhibiting part (22d) comprising an annular flange is provided at the outer peripheral edge of a carrier (22). Thus, when a planetary gear mechanism is operated, an internal gear member (24) partially projects outward from the annular shape and deforms. When doing so, the projecting deformation part of the internal gear member (24) comes into contact with the inner peripheral surface of the deformation inhibiting part (22d). With this configuration, deformation of the internal gear member (24) is effectively inhibited.

Description

technical field [0001] The present invention relates to a seat belt retractor, which is installed in a vehicle such as an automobile, and is wound by a spool for restraint, and a seat belt device provided with the seat belt retractor. The passenger's seat belt, the rotation of the motor is decelerated by the power transmission mechanism using the planetary gear mechanism and transmitted to the above-mentioned spool. Background technique [0002] Conventional seat belt devices installed in vehicles such as automobiles prevent the occupant from flying out of the seat by restraining the occupant with the seat belt in an emergency such as when a large deceleration acts on the vehicle during a collision . [0003] Such a seat belt device is provided with a seat belt retractor that winds up the seat belt. This seat belt retractor has a spring mechanism such as a coil spring that constantly urges the spool around which the seat belt is wound in the direction in which the seat bel...
