A locking-aid device is disclosed for a lock, especially for a vehicle door lock or flap lock, in which a pneumatic single-acting locking-aid drive is provided for displacing an abutment for a rotary latch out of a catch position into a locking position, in which the abutment is secured positively by means of a detent pawl. According to the invention the detent pawl can be lifted out, during the opening of the lock, independently of a movement of the locking-aid drive by means of an operative connection. This can be brought about purely mechanically or by means of a separate drive for lifting out the detent pawl during the opening of the lock, so that the abutment can always jump into its catch position immediately during or after the opening of the lock and thus also allows a successive multiple activation of the locking-aid assistance.

Locking-aid device for a lock

A motor veicle compartment closure lock with a locking wedge (2) attached on the closure, and lock elements attached on an opening frame for the closure. The locking wedge (2) can be retracted, in a powered way, from an extended, open position into a pushed-in, locked position and, for this purpose, is coupled by a lever mechanism (3) to a power transmission element (5) with a powered drive. The powered drive can be built especially small and light because the drive is made as a drive that operates only in one direction (locking direction) and returns automatically in the opposite direction. Power transmission element (5) is slaved or can be slaved to the locking wedge (2) in the locking direction and moves freely in the opposite direction. A shifting lever (6) is provided that is carried by the power transmission element (5) in the locking direction and is spring-loaded in the opposite direction. The shifting lever has an engaging part (7) that moves in a shifting link (8), and the engaging part (7) can be brought by a movement in the locking direction, from an open rest stop (9), to lie against a locking stop (10) and can be brought, by renewed movement in the locking direction, from the locking stop (10) back again to the open rest stop (9).

Vehicle hood or door lock

The invention concerns a securing device for swivelling components of vehicles, in particular for engine hoods of motor vehicles. A securing hook which, after the release of the swivelling component, initially maintains a catch connection between this swivelling component and a fixed location mating component until the securing hook is pivoted into a release position by means of a manipulator. The manipulator, which is recessed when the swivelling component is locked, is automatically transferred into an accessible operating position by utilization of a forced advancement of the swivelling component relative to the mating component initiated by the release procedure. A control edge effectively connected to the manipulator and supported on the mating component is moved in the opening direction of the securing hook by sliding along the mating component. In order to permit an increase in the automatic manipulator advancement without doubts about safety and without sacrifices to operational comfort, the control edge is part of a control hook which is supported so that it can move relative to the securing hook and the motion of the control hook is only coupled to that of the securing hook after it is in advance of the latter.

Securing device for engine hoods of motor vehicles with self presenting

A locking device for lock components, for example on vehicles, with two rotary closures which are arranged at a distance from one another and are connected by means of a mechanical transmission element to form a synchronously rotating closure unit and which interact with two catch bolts assigned to the two rotary closures, each located in a housing having an orifice adapted to receive the catch bolts. The two rotary closures of the closure unit, in their release position, are each blocked by means of an associated control member against rotation into locking engagement with the associated catch bolt. The control members are movable into an unblocked position in response to penetration of the catch bolts into the orifice of the housing, and the locking advance of the rotary closures is permitted only after both catch bolts have penetrated fully into the orifice in the housing.

Locking device for lock components in/on vehicles

An actuating device is provided for closing and opening a door or lid lock and correspondingly switching a light on and off during the opening and closing of the door or lid. This actuating device also makes it possible to switch off the light permanently when the door or lid is open, because the switch is switchable indirectly per se as a result of movements of a rotary latch and can be switched manually into its switch-off position independently of the actuating device.

Actuating device for an electrical switch

Motor vehicle door lock or the like with a pivotally mounted locking catch (3), a pivotally mounted pawl (4) which blocks the locking catch (3) in a preliminary locking position and a main locking position, and with a locking mechanism (5) for operating the locking catch (3) and pawl (4). The locking mechanism (5) has an outside release lever (6), and when outside release lever (6) is operated, pawl (4) can swing into a release position freeing locking catch (3), e.g., by being lifted. The manipulation of the lock is improved since, in the opening movement, when the locking catch (3) is in the main locking position and the release lever (6) is operated, the pawl (4) is swung into the release position, where it is retained independently of the further operation condition of outside release lever (6) until the locking catch (3) has passed the preliminary locking position.

Motor vehicle door lock

The invention concerns a power-assisted lock for doors, hatches hoods or hard tops of vehicles and the like. In addition to a known pivotal latch and a catch for a releasable engagement with the pivotal latch there is a control disc pivotally mounted in the housing of the lock. A manual or power actuated drive means is attached to the control disc for the closing and opening operation. The pivotal latch and the control disc have a drive connection providing for limited play. The arrangement together with the catch leads to a locking of the control disc before a closing operation and an unlocking of the control disc by turning the pivotal latch during the closing operation of the lock. The pivotal latch has the usual pre-lock position.
