[0003] However, with such a motor tractor, there is a risk of discomfort to the passenger if the winding of the webbing is resumed without the occupant having released his arm or the like from the webbing
In particular, where a large part of the webbing has been rolled up, the passenger's arm or the like will be easily pulled by said webbing, which may aggravate the passenger's discomfort

[0029] FIG. 1 is a front sectional view schematically describing the overall configuration of a motor tractor 10 according to a first embodiment of the present invention.

[0030] As shown in FIG. 1 , the motor puller 10 includes a frame 12 . The frame 12 includes a substantially disk-shaped back plate 14, and the motor tractor 10 is mounted to the vehicle body by fixing the back plate 14 to the vehicle body using connecting members (not shown) such as screws. main body. A pair of support plates 16, 18 extend parallel to each other from both edges in the width direction of the back plate 14, and between the support plates 16 and 18, a reel shaft 20 serving as a winding shaft is rotatably provided. and made by die casting or the like.

[0031] The reel 20 is composed of a substantially cylindrical reel body 22 and a pair of flange portions 24 , 26 formed into substantially disc shapes at both ends of the reel body 22 , and has a drum shape as a whole.

[0032] The bottom end...

Abstract

A motor retractor , comprising: a winding shaft which winds up a webbing for restraining a vehicle passenger; a motor which rotates the winding shaft in a webbing winding-up direction; and a control portion which, after release of the webbing wearing state of the passenger: drives the motor to cause the webbing to be wound up around the winding shaft; stops the motor when an overload on the motor is detected during the winding-up; redrives the motor after a predetermined time having elapsed after the motor is stopped due to detection of the overland, and adjusts, at the time of the redriving, a driving state of the motor according to the time of driving the motor that has elapsed before the overload detection, is provided.

Description

technical field [0001] The present invention relates to a tape winding device, in particular to a motor puller capable of winding up a tape by using a motor to rotate a winding shaft. Background technique [0002] A conventional motor puller is configured to interrupt power feeding to the motor when a passenger's arm or the like grabs the belt during winding to overload the motor (see Japanese Patent Application No. 2004-244011). With this motor tractor, the power feed to the motor is resumed after a predetermined time has elapsed after the power feed to the motor has been interrupted, and therefore, the passenger can lift his arm or the like from the belt within the above predetermined time. The piece is unwound, and, by resuming the power feed to the motor, the winding of the strip can be effected. [0003] However, with such a motor tractor, there is a risk of discomfort to the passenger if the winding of the webbing is resumed without the occupant having released his ar...
