Safety belt restraining system with securing mechanism for mechanical sensor

摘要

A control mechanism for a mechanical sensor at a safety belt reeling device of a safety restraining mechanism has a housing and a mechanical sensor pivotably connected to the housing. A locking device is connected to the housing and has a locking position for securing the mechanical sensor against pivoting and a release position for releasing the mechanical sensor. The locking device has an initial disengaged position before mounting of the housing to the vehicle and a stand-by position in which the locking device still secures the mechanical sensor. A sensing device for sensing belt removal from the safety belt reeling device is provided and cooperates with the locking device in the stand-by position such that, at a certain degree of belt removal, the sensing device moves the locking device from the locking position into the release position. A control member for controlling the locking device is provided and has an inactive position and an active position. The control member is moved from the inactive position into the active position when the housing is fastened to the vehicle. In the inactive position the locking device is forced by the control member into the initial disengaged position and, when the control member is moved into the active position, the locking device is moved into the stand-by position.
