A lock unit for a vehicle includes a rotatable catch biased in an opening direction about a catch rotation axis toward an open position of the lock unit in which a first recess of the catch is configured to receive a striker of the vehicle. Additionally, the catch includes a second recess disposed before the first recess in the opening direction. A pawl including a slot rotatable about a fixed pawl pivot axis is biased toward both the catch and the pawl pivot axis. The pawl includes a blocking arm which extends into the second recess of the catch when the lock unit is in a secondary latched position. A blocking lever of a ratchet abuts the blocking arm of the pawl against the catch in a primary latched position of the lock unit preventing rotation of the pawl away from the catch. When the lock unit is forced from the secondary latched position to the primary latched position, the pawl moves in a longitudinal direction of the slot avoiding the rotational blocking action of the ratchet.

A vehicle door lock (1) having a fork (2) which rotates about a first axis (A) between a release position and at least one lock position engaging a fixed striker (15), and a latch (3) which rotates about a second axis (B), is loaded elastically towards the fork (2), and has a catch portion (25) which clicks onto a tooth (11) of the fork (2) to lock the fork (2) releasably in the lock position. The fork (2) is defined by a main body (6) made of rigid material, and by an outer coating (7) made of relatively yielding material and having, adjacent to the tooth (11), a slot (33) defining a peripheral edge (34) which flexes inwards of the slot (33) when struck by the catch portion (25) of the latch (3) engaging the tooth (11) of the fork (2). The main body (6) has a recess (36) close to the root of the tooth (11); and the slot (33) is at least partly superimposed over the recess (36) to allow the peripheral edge (34) to flex inwards of the slot (33) wherever the catch portion (25) of the latch (3) strikes the fork (2).

In a device for operating locks (16) on doors or hatches of vehicles, a fixed support (10) is a arranged on the door. A moving unit (20) is mounted (11, 12), such as to pivot on the support (10), belonging to which is at least one handle (21). Spring loading (25, 26) ensures the unoperated moving unit (20) is held in a flat rest position on the support (10). On operating the handle, the moving unit (20) must be pivoted against said spring loading, whereby the lock (16) is operated. A damping unit (30) ensures that the returning moving unit (20) pivoting action is decelerated. A reliable, economical damping unit (30) is obtained, whereby an elastic body (31) is arranged in at least one position on the moving unit (20) which extends outwards with a projection (32). On the return movement (39) into the rest position the extending projection (32) is deformed against a fixed counter-surface (40), whereupon the movement energy is largely dissipated. On reaching the rest position, the deformed projection (32) is supported against the counter-surface (40).

A fitted plug attached to the latch striker is configured for partial insertion into the fishmouth of the latch body when the latch striker is engaged with the latch.

A latch device comprises a latch lock operated to engage a striker. When the latch lock engages the striker, a cam disk contacts the latch lock slidably to rotate the latch lock, thereby preventing loose between the lock and the striker. The latch lock comprises a limiting part, which contacts with a locking plate, then the latch lock rotates, such that the limiting part separates from the locking plate, thereby engaging the latch lock and the striker with small force.

A latch mechanism comprises a latch bolt rotatably mounted about a pivot on a chassis. The latch bolt is movable from an open condition, in which it is free to receive a striker of a motor vehicle, to a closed condition in which the striker is retained by the latch bolt. The latch bolt comprises an overmold of elastomeric material, which defines first, second and third buffers. The third buffer is adapted to cooperate with an abutment on the chassis to absorb over-travel of the striker when the door of a motor vehicle carrying the latch mechanism is closed.

The opening control includes a handle, movable in rotation relative to the casing at least between leveling, ejection and opening positions, an ejection lever connected to the handle by at least one common axis of rotation with this handle and an electric actuator for controlling a pivoting of the ejection lever between at least one ejection position and a non-ejection position. In particular, the opening control includes a biasing member connected to the ejection lever and configured to exert a force for returning the lever towards the ejection position according to an ejection direction of rotation, and means for blocking the lever in its non-ejection position. The blocking means are capable of cooperating with the lever in order to release the lever when the handle is displaced in a direction of rotation opposite to the ejection direction, by application of an external push force on the handle.

A lock is provided for a door of a motor vehicle. The lock includes a closing mechanism designed for coupling with a lock striker along a direction of relative coupling.

A hood latch having an extra-long fishmouth for enabling a vehicle hood to deflect downwardly upon impact, such as when hit by a pedestrian in a frontal crash. To prevent this deflection when the hood is slammed shut in ordinary use, a stop lever is pivotally mounted to the latch housing. The stop lever features first and second arms defining a slot therein. One arm has a proboscis thereon and is biased to align the slot with the fishmouth, with the proboscis jutting into the fishmouth. The proboscis receives an impact from the striker and rotates the stop lever to a blocking position wherein the non-proboscis arm intercepts the striker and prevents it from reaching the bottom end of the fishmouth. In the closed position the ratchet retains the striker at an intermediate depth in the fishmouth, enabling the striker to travel toward the bottom end thereof.
