摘要:
A stowable vehicle seat, which is stowed by folding a seat back toward the side of a seat cushion, releasing a floor lock while the seat back is in a superposed state on the seat cushion, and lifting the vehicle seat up toward the vehicle body side. The vehicle seat is fixed by connecting a striker disposed on the back face of the seat back with a dragger unit disposed on the vehicle body side. After an operation to release locking of the dragger unit, separation of the striker from the dragger unit is estimated, and a dragger motor is driven so that a latch of the dragger unit is moved to the initial position.

A locking mechanism of the key lock type or code lock type for installation in a door of a vault or safe, includes at least one locking bolt for movement between a locking position in which a door is locked and an unlocking position in which the door is released for opening, an electromechanical actuator connected to the locking bolt for moving the locking bolt between the locking position and the unlocking position, a time delay circuit so interacting with the actuator as to delay operation of the actuator for a specified time period, with the time delay circuit being so positioned as to be inaccessible upon closed door and including an activation input for cooperation with a switch accessible from outside such that the time delay circuit is activated.

A lock includes a hollow lock body with a plurality of aligned first transverse holes, a cylindrical key plug rotatably disposed inside the lock body and having a plurality of second transverse holes aligned with the first transverse holes, and a plurality of tumbler pins extending into each set of aligned first and second transverse holes. The lock further includes a first control switch actuated by inserting a key into the key plug, a second control switch actuated by rotating the key plug relative to the lock body, and an electrical control circuitry including a first timer circuit connected to the second control switch, a second timer circuit connected to the first control switch, a warning device and an electromagnetic control unit both actuated by the second timer circuit. The first timer circuit disables the second timer circuit for a predetermined time period when the first timer circuit is actuated. The warning device sends out alarm signals and the electromagnetic control unit prevents the rotation of the key plug for a predetermined period of time if the lock has not been opened after the second timer circuit has counted down a preset time period.
摘要:
A keyless combination lock is protected against manipulation by the inclusion of a rotary member turned by rotation of the dial of the lock and which, after excessive rotation from a datum position, such as is likely to occur under conditions of manipulation, serves to move a protective member into an operative position such that operation of the lock is impossible, e.g. by isolating the probe of the lock from the combination wheels. The rotary member is also connected to mechanism for returning it to its datum position after a time delay and arrival at the datum position serves to return the protective member back to an inoperative position if it has previously been moved to its operative position. The return mechanism may start to operate as soon as the rotary member is turned from its datum position and may include a spring which is progressively stressed as the rotary member is turned. The stress in the spring then serves to return the rotary member to its datum position at a rate determined by an escapement mechanism.
