The invention provides an electronic vehicle sensing type safety belt retractor assembly which comprises a rotatable belt winding drum, a driving device and a driving device. The locking device is used for locking the tape winding drum in the pulling-out direction of the woven tape; the belt sensing assembly is arranged to drive the locking device to lock the belt winding drum when the ratchets are meshed; the electromagnetic switch is provided with a pawl which is subjected to spring force in the direction of meshing with the ratchets; the return assembly is used for locking the pawl at a position which is not meshed with the ratchet at a locking position within a set braid pull-out length; the restraining spring is arranged to provide driving force for limiting the return assembly to the locking position when the tape winding drum rotates in the pulling-out direction of the woven tape and exceeds the set length of the woven tape, and the restraining spring is located at the position for releasing the return assembly when the tape winding drum rotates in the direction opposite to the pulling-out direction of the woven tape. According to the retractor assembly, the function that the electronic vehicle sensing type safety belt can be worn for the first time when the electronic vehicle sensing type safety belt is not powered on is achieved.
本发明提供一种电子车感式安全带卷收器总成,包括:以可旋转的的卷带筒,其上设有织带;在所述织带的拉出方向锁止卷带筒的锁止装置;具有棘齿的带感总成,其设置为在棘齿啮合时驱动锁止装置锁止卷带筒;电磁开关,其具有在与棘齿啮合的方向受弹簧力作用的棘爪;回位组件,在设定织带拉出长度内,其在锁止位置将棘爪锁止在与棘齿不啮合的位置;以及抑制弹簧,其设置为在卷带筒沿织带的拉出方向转动且在超过设定织带长度时,提供将回位组件限定在锁止位置的驱动力,在所述卷带筒沿织带的拉出方向的相反方向转动时处于释放所述回位组件的位置。本发明的卷收器总成实现了电子车感式安全带在未通电时的首次可佩戴功能。
