Embodiment Construction

[0038] Hereinafter, the mode for implementing the present invention will be explained using the drawings.

[0039] figure 1 It is a diagram schematically showing a seat belt device including an embodiment of the seat belt retractor according to the present invention.

[0040] Such as figure 1 As shown, the seat belt device of this example is basically the same as the conventional three-point seat belt device. In the figure, 1 represents the seat belt device, 2 represents the vehicle seat, 3 represents the seat belt retractor arranged on the vehicle body near the vehicle seat 2, and 4 represents the retractable seat belt retractor. The seat belt on the reel of the seat belt retractor 3 and the front-end belt holder 4a is fixed to the vehicle floor or the seat belt of the vehicle seat 2. 5 denotes the seat that will be pulled out from the seat belt retractor 3 The seat belt 4 is a belt guide and anchor that guides the occupant's shoulders, 6 is a tongue that is slidably supported ...

Abstract

Further effectively improve quietness and more stable power transmission. The ring-shaped internal gear member ( 24 ) is formed of a noise generation suppressing material whose strength is lower than that of metal. In addition, a deformation suppressing portion (22d) formed of an annular flange is provided on the outer peripheral edge of the carrier (22). Therefore, when the planetary gear mechanism is in operation, the internal gear member (24) partially protrudes and deforms outward in the annular shape. At this time, the protruding and deformed portion of the internal gear member (24) comes into contact with the inner peripheral surface of the deformation suppressing portion (22d). Accordingly, deformation of the internal gear member (24) is effectively suppressed.

Description

Technical field [0001] The present invention relates to a seat belt retractor and a seat belt device provided with the seat belt retractor. The seat belt retractor is equipped in automobiles and other vehicles and is wound by a reel for restraint For the seat belt of the occupant, the rotation of the electric motor is reduced by a power transmission mechanism using a planetary gear mechanism and transmitted to the reel. Background technique [0002] For conventional seat belt devices equipped in automobiles and other vehicles, in an emergency such as when a large deceleration acts on the vehicle during a collision, the seat belt restrains the occupants to restrain the occupants from flying out of the seat. . [0003] A seat belt retractor for winding the seat belt is provided in this seat belt device. The seat belt retractor is equipped with a spring mechanism such as a coil spring that always energizes the spool on which the seat belt is wound in the seat belt winding direction....
