A motor vehicle door lock which is equipped with a locking mechanism substantially comprising a catch and pawl. Furthermore, a locking pin is provided for interaction with the locking mechanism. Furthermore, there is a damping element for a locking mechanism component and/or the locking pin. Finally, the configuration includes at least one spring which is assigned to the locking mechanism. According to the invention, the spring at least partially abuts the damping element.

An exemplary damper module is configured for use with a latchbolt assembly, and generally includes a mounting bracket, a first slowing mechanism, and a second slowing mechanism. The latchbolt assembly generally includes a drive member, a latchbolt, and a retractor connected between the drive member and the latchbolt. Each of the slowing mechanisms is independently operable to slow the extension speed of the latchbolt. The first slowing mechanism includes a rack gear and a rotary damper including a pinion gear. The rack gear is configured to be mounted to the drive member, and the rotary damper is mounted to the mounting bracket. The second slowing mechanism includes a slowing arm and a biasing member engaged with the slowing arm. The slowing arm is movably mounted to the mounting bracket and is configured to engage the retractor.

A door silencing mechanism and methods to eliminate latch noise associated with a door latch having a spring latch bolt and a bolt housing are described. This mechanism and methods can include an actuator having a first end and a second end and moveable between a first position and a second position. This mechanism can also include a device coupled to the first end of the actuator to maintain the spring latch bolt within a bolt housing using the second end of the actuator when the device holds the actuator in the first position and to release the spring latch bolt from within the bolt housing by moving the second end of the actuator in response to the actuator moving to the second position in response to contact with a doorjamb.

A door latch assembly is provided with enhanced acoustic dampening characteristics, and includes a door bolt assembly having an inside barrel and an outside barrel configured for accommodating reciprocal sliding action of the inside barrel between a latch position and a release position. At least one barrel acoustic isolator is associated with at least one of the inside barrel and the outside barrel, and is configured for dampening sound generated by the reciprocal action.

An exemplary noise-reducing mechanism for door hardware includes a housing, a damper, and a stop. The door hardware includes a first component and a second component, and an operational movement of the door hardware causes relative movement of the first and second components. The housing is mounted to the first component, and the damper is mounted to the housing. The stop is mounted to the second component such that the stop engages the damper during the operational movement. The damper is configured to slow the operational movement, thereby reducing noise generated by operation of the door hardware.

The present invention relates to an improved carabiner system, including an impact-dampening cushion around the external surface of the frame for cushioning damage during a fall or collision and to reduce sound from loose or swinging carabiner collisions. Additional surface routing and through holes provide improved register between the carabiner frame and the over-molded cushion layer.

The invention relates to a motor vehicle door lock comprising a locking mechanism, also at least one locking element (3), an electric drive (5, 6, 7) for the locking mechanism, and at least two stops (20, 21, 22, 27) for the electric drive (5, 6, 7) and/or the locking element (3), wherein one of the stops (20, 21) is associated with the locking element (3) and the other stop (22, 27) is associated with the electric drive (5, 6, 7) and both stops (20, 21, 22, 27) are arranged on a common stop contour (23).

A door latch mechanism including a latch housing, a bolt having a proximal end with a head and a distal end having a latch, a hub including a central bore for receiving a spindle, a lever actuated by rotation of the hub, the lever including a slot in a top portion of the lever receiving the head of the bolt such that the lever and the bolt move together in both rearward and forward directions.

A latch bolt buffer structure is disclosed for lock body, including outer lining board for lock body, latch bolt assembly, damper, connecting rod, latch bolt poking mechanism, dead bolt mechanism, box cover and box bottom assembly for lock body. Latch bolt assembly includes latch bolt, friction bolt, pull rod, spring, limiting silencing ring, and slider. The box bottom assembly includes an inner lining board for the lock body, a silencing block for the dead bolt, a silencing block for the latch bolt, a box bottom, a positioning plate, a spring, a fixing nail and a damper. Manufacturing parts made of sound-absorbent plastic material is adopted to replace metal parts, or separating metal parts by sound-absorbent plastic material is adopted to reduce noise generated by friction. At the same time, the damper buffer function is used to reduce sound generated by parts collision when lock body is working.

This invention relates to a latch (preferably a slam latch) and to methods of operating a door/gate/panel using the latch. The latch comprises: (i) a mounting body; (ii) a latch bolt mounted relative to the mounting body for movement between a locking position and an unlocking position, said latch bolt having a keeper-engaging region extending from the mounting body and terminating at a keeper-engaging end; and (iii) a keeper having at least a first wall and a second wall which are spaced to define an opening for receiving the keeper-engaging region, wherein the first and second walls are adapted to engage the keeper-engaging region of the latch bolt when the latch bolt is in the locking position.
