ABSTRACT:
A ratchet type vehicle closure latch is secured to a vehicle door by a pair of bolts. One is located in proximity to engaged teeth of a rotatable ratchet and pawl and the other is located in proximity to engaged portions of the ratchet and a striker. The closure latch has a plastic housing that includes a thin integral plastic sleeve that breaks away in service to provide a sleeve bearing that eliminates metal-on-metal contact between the rotatable ratchet and a ratchet stud. The ratchet stud and a pawl stud hold several parts of the door latch together. The door latch has several non-metallic parts and an insert molded ratchet for minimizing the metal-on-metal engagement, operational noise and lubrication requirements. Some parts are non-handed and other parts are identical to reduce manufacturing costs.
