Abstract
The utility model provides a counter impact resisting unlocking-prevented locking device which comprises a double-stopping-surface stopping tooth board (3) and a double-stopping-surface dialing wheel (4). According to the counter impact resisting unlocking-prevented locking device, the double-stopping-surface stopping tooth board which is provided with a left stopping surface and a right stopping surface that are vertical respectively and the double-stopping-surface dialing wheel that is correspondingly provided a pawl stopping surface and an auxiliary surface that are vertical respectively are adopted. In operation, the double-stopping-surface stopping tooth board and the double-stopping-surface dialing wheel respectively contact with the pawl stopping surface and the auxiliary surface through the left stopping surface and the right stopping surface, thereby forming a double-stopping-surface support. Counter impact of a seat is resisted through a force bearing balance characteristic of double stopping surfaces, thereby eliminating unlocking trend of the dialing wheel. The problems/defects of low counter impact resistance and non-reliable locking in the prior art are overcome. Through the double-stopping-surface support, the following purposes are obtained in a hand-operated angle regulator of the automotive backrest: improved counter impact resistance, and reliable fixation.
Description
Technical field
The utility model relates to the release blocking device of the moving hands at the back recliner of automobile seat, specifically is meant the release blocking device of a kind of degeneration-resistant moving impact of the guide plate that is used for the manual recliner of the Control of Automobile chair back and mutual release of moving tooth plate or locking.
Background technology
