    Abstract: An electrically powered drive system for automatically opening and/or closing the door of a motor vehicle. An electric drive assembly including a motor and an irreversible gear box is coupled to the hinge of the door by means of a normally-disengaged clutch. Control means are provided for selectively energizing the motor and clutch. In a preferred embodiment a solenoid is coupled to the system for unlatching the door preparatory to energization of the drive motor.

    Abstract: A door closer (10) includes an exterior housing (11), a spring assembly (12), a ratchet assembly (13), and a clutch assembly (14). The housing has a central tube (17), drive collar (23), a top end cap (52), and a bottom end cap (65). The drive collar includes an indexing pin channel (41) and indexing pin (42) which includes a pawl (45) having a contact surface (47) and a curved bearing surface (48). The spring assembly includes a shaft (73), a spring stop (80), and a helical torsion spring (106) positioned upon the shaft. The ratchet assembly resides within drive collar and includes ratchet wheel (111) having an annular array of ratchet teeth (112) configured to mesh with the pawl of the indexing pin. Each tooth has an undercut contact surface (113) and a curved bearing surface (114). The clutch assembly includes a bottom disc (120) and a top disc (121).
