초록 ▼

A self-locking belt retractor has a vehicle-sensitive controlled blocking system in which a mass (14) moves a locking lever (17) engaged in the toothing (29) of a controlled disk. The sensor mass (14) is fitted in a holder part (10) on a support surface (23) that can be tilted in case of vehicle accelerations, the locking lever (17) on the end (19) facing away from the engaging tip (18) being connected to the sensor mass (14) in a form-fitting manner and forming a support (21). A form fit occurs in an extension (15) of the sensor mass (14) which protrudes through a hole (33) in the contact surface (23) of the holder part (10). A projection (31) projecting into a hole (33) is provided at the border of the hole (33) facing the locking lever (17) that is contacted by the locking lever (17) in case of a deflection.

대표청구항 ▼

1. A self-locking belt retractor having at least one vehicle-sensitive controlled blocking system for a belt winding shaft in which a vehicle-sensitive sensor mass (14) has an engaging tip (18) that moves a locking lever (17) and is engaged in a toothing (29) of a control disk when activated, so that the control disk is stopped in its rotary motion together with the belt winding shaft and consequently activates the blocking system, the sensor mass (14) being arranged in a vertical position in a holder part (10) on a support surface (23) that can be tilted in the holder part (10) in response to vehicle accelerations, the locking lever (17) being coupled with the sensor mass (14) on an end (19) facing away from the engaging tip in a form-fitting manner and forming a support (21), the form fit occurring in an extension (15) of the sensor mass (14) which protrudes through a hole (33) in the contact surface (23) of the holder part, the hole (33) having a border facing the locking lever (17) and forming a projection (31) projecting radially inwardly through a circle formed by the hole (33), the projection being contacted by the locking lever (17) when the sensor mass (14) is activated. 2. The belt extractor according to claim 1, wherein the projection (31) is configured as a tongue projecting into the hole (33), the tongue extending in a longitudinal direction of the locking lever (17). 3. The belt extractor according to claim 1, wherein the projection (31) has a thickness that decreases to an edge toward its free end. 4. The belt extractor according to claim 1, wherein on one of the sensor mass (14) and the holder part (10) a post (16) is arranged for an alignment of the sensor mass (14) in a predefined position, the post engaging into a recess (11) on the other one of the sensor mass (14) and the holder part (10). 5. The belt extractor according to claim 4, wherein at least one projection (22) is arranged on one of the sensor mass (14) and the holder part (10) that engages into a recess (13) on the other one of the sensor mass (14) and the holder part (10). 6. The belt extractor according to claim 4, wherein a pair of the posts (16, 22) are provided having a tapered cross-sectional surface in the areas engaging into the recesses (11, 13), as a result of which the sensor mass (14) can swivel in the recesses (11, 13).
