Embodiment Construction

[0034] exist figure 1 Among them, the lock is generally indicated by 8, which includes a lock assembly 10 and a striker 14 corresponding thereto. The lock assembly 10 is located on a lock plate indicated at 12 . Typically, the lock disc 12 is located within the vehicle door, which is not clearly shown. A striker 14 is typically mounted on the vehicle body (also not clearly shown) and in use said striker is engaged by the lock assembly 10 to close the vehicle door, as will be briefly described below.

[0035] The lock assembly 10 includes a deadbolt 16 for rotation on a deadbolt shaft 18 . The locking bolt 16 is deflected counterclockwise by the locking spring 17, and a spring stop 20 prevents it from exceeding figure 1 Rotation in position shown. The latch 16 has a port 22 for receiving a striker, a safety base 24 and a closure base 26 . The bolt also includes a drive base 28, the purpose of which will be discussed further briefly.

[0036] The lock assembly 10 has a paw...

Abstract

A latch assembly includes a latch bolt for engaging an associated striker. The latch bolt has an open position, a safety position and a closed position, which positions correspond to an open condition, a safety condition and closed condition, respectively, in the latch assembly. The latch assembly further includes a pawl for releasably retaining the latch bolt in the safety position and the closed position. The latch assembly includes a power closure mechanism that applies a drive load to the latch bolt to drive the latch bolt from the safety position to the closed position and a pivotably mounted driving member with a first portion which in use abuts against the latch bolt in response to powered closure. The powered closure results from movement of the pivot of the driving member combined with abutment of a second portion of the driving member against a bearing surface or a bearing device.

Description

technical field [0001] The present invention relates to a lock, especially but not limited to a lock for a vehicle door. Background technique [0002] Known vehicle doors include a door seal of elastomeric material secured to the periphery of the door, said seal being compressed into the door opening and into contact with the periphery of the door opening when the door is closed. In the trend of modern automobile manufacturing, it requires a large door seal load to reduce the noise generated by the wind when the vehicle is running. Consequently, increased force must be applied to the door when the door is closed by the operator in order to ensure that the latch mechanism will close the door. [0003] A consequence of the larger seal load is that the operator is required to apply an increasing load to the door to ensure that the lock closes the door. One known solution to this problem is to provide a powered closed latch mechanism that drives the lock from the closed safe p...
