摘要： A webbing retractor is provided with a lock mechanism. The webbing retractor further comprises a bobbin, a webbing-holding member and a webbing. The bobbin has a drum portion and a pair of flanges arranged on opposite ends of the drum. The flanges define grooves formed in a mutually-opposing relationship and angularly extending over a predetermined length in a webbing-releasing direction as a first direction of rotation. The webbing-holding member extends between the grooves. The webbing is secured at one end thereof in the bobbin, wound back about the webbing-holding member at a first portion thereof apart from the one end thereof toward an opposite end thereof, and then wound in layers around the drum portion in the first direction of rotation at a second portion thereof closer to the opposite end than the first portion.

摘要： A retractor for use with a seat belt is capable of releasing a state of end lock easily without using a complicated structure of the lock operation means for operating the lock means in the case of an emergency of a vehicle. There are provided pawls (16, 13) capable of checking the rotation of the bobbin (3) in the webbing drawing direction when the pawls are engaged with inner teeth (2a, 2c) arranged on the side plates (1a, 1b) of the retractor base (1). The pawls (16, 13) are supported so that they can be relatively moved with respect to the bobbin (3) in the rotational direction of the winding shaft by a predetermined distance. In the normal operation, the ratchet wheel (18) follows the rotation of the bobbin (3). When the ratchet wheel (18) is relatively rotated with respect to the bobbin (3) in the webbing winding direction, the pawls (16, 13) are engaged with the inner teeth (2a, 2c). When the pawls (16, 13) are relatively rotated with respect to the bobbin (3), one end of the oscillating lever member (20) to reverse the ratchet wheel (18) in the webbing winding direction is connected to the ratchet wheel (18), and the middle portion is engaged with the pawl (16), and the other end is engaged with the bobbin (3).

摘要： A retractor for a seat belt includes a winding force reducing mechanism for reducing a webbing winding force when an occupant wears the seat belt. The retractor includes a base; a winding shaft supported rotatably on base for winding a webbing; a first winding spring for energizing the winding shaft in a webbing winding direction; a second winding spring disposed on the winding shaft in parallel to said first winding spring; and gear unit interposed between the winding shaft and the second winding spring for applying the energizing force of the second winding spring to the winding shaft in the same direction as the energizing force of the first winding spring and for tightening the second winding spring in an elastic energy storing direction by means of the energizing force of the first winding spring. The gear unit is structured such that, when the seat belt is in use, the elastic energy of the second winding spring stored therein can act in a manner to cancel the energizing force of the first winding spring so that a reduced energizing force in the webbing winding direction can be applied to the winding shaft.

摘要： In a retractor for seat belt according to the present invention, a stopper mechanism 50 is provided between a side plate 101a and a bobbin 1. The stopper mechanism 50 is composed of a through hole 110 formed in the side plate 101a by drawing the same inwardly, and three lock pieces 3 which are respectively disposed on the locking base side end face of the bobbin 1 and are engageable with the inner peripheral surface of the through hole 110 so as to stop the rotation of the bobbin 1 in the webbing drawn-out direction thereof with respect to the side plate 101a. In addition, a control plate 4 is interposed between a locking base 5 and the bobbin 1. When a torsion bar 2 is torsionally deformed and in turn the amount of rotation of the bobbin 1 in the webbing drawn-out direction thereof with respect to the locking base 5 reaches or exceeds a predetermined amount, the control plate 4 brings the lock pieces 3 into engagement with the inner peripheral surface of the through hole 110 so as to restrict the deformation amount of a plastically deforming member to a predetermined range of amount.

摘要： A retractor for use with a seat belt is capable of releasing a state of end lock without using a complicated structure of a locking mechanism for operating the locking of the retractor in the case of an emergency of a vehicle. The retractor contains an angular engaging surface at one end of a winding shaft, that engages with a retractor base at certain portions. The angular engaging surface has a groove in the direction of a circumference of the winding shaft into which the portions may be engaged. This groove helps to prevent the displacement of the winding shaft in the direction of thrust and allows for superior locking.
