Embodiment Construction

[0027]

[0028] First, the overall structure of the seat belt retractor 10 related to the embodiment of the present invention will be described.

[0029] The overall structure of the safety belt retractor 10 is image 3 is schematically shown in the exploded perspective view of . Such as image 3 As shown, the seat belt retractor 10 has a frame 12 .

[0030] The frame 12 has a plate-shaped rear panel 14 whose thickness direction extends generally along, for example, the left-right direction of the vehicle. The seat belt retractor 10 is mounted on the vehicle body since the rear panel 14 is fixed to the vehicle body by, for example, fixing means (eg, bolts, etc.) near the lower end portion of the center pillar.

[0031] The foot plate 16 is formed by bending inwardly in the lateral direction of the vehicle (approximately the left-right direction of the vehicle) from one lateral end of the rear panel 14 substantially in the longitudinal direction of the vehicle. The foot p...

Abstract

In the seat belt retractor (10), the gear box (70) rotatably supports the other end of the shaft (162) of the locking pawl (160), and is fixed to the frame (12) by engaging pins (182, 184). superior. That is, the engagement pin (182) is matched with the engagement hole (186) of the foot plate (16), and the engagement pin (184) is on the side opposite to the side where the engagement pin (182) is placed on the sliding track of the tooth bar (68). , fits into the engaging hole (188), and is positioned to move more in the sliding direction of the rack gear (68) than the engaging pin (182). According to the seat belt retractor (10), even if the gear case (70) attempts to move relative to the foot plate (16), the engagement pins (182, 184) resist it, thereby preventing the gear case (70) from moving. That is, it is possible to suppress or prevent a change in the support position of a specific component that is provided in the vicinity of the sliding track of the slider of the pretensioner.

Description

technical field [0001] The present invention relates to a webbing retractor, which winds and accommodates a seat belt restraining the body of a passenger in a vehicle. Background technique [0002] The seat belt device restrains the body of a vehicle occupant seated on a vehicle seat by a slender belt-shaped seat belt, and is equipped with a seat belt retractor fixed to the vehicle body at the side of the seat. The belt retractor has a spool whose axial direction extends approximately along, for example, the longitudinal direction of the vehicle. The longitudinal proximal end side of the webbing is fixed to the reel, and the webbing is accommodated in a state of being wound in layers around an outer peripheral portion of the reel. [0003] The seat belt thus accommodated in a state of being wound around the spool is pulled out, and the pulled out seat belt is fastened around the body of the occupant in the vehicle. In this state, since the tongue plate provided at the pred...
