Abstract: In a first aspect, the invention is directed to a closure latch for a vehicle closure panel, having at least three lock states all of which are achieved using a single control member. The control member may be movable to at least three positions to achieve the lock states. A single motor may be used to move the control member between the positions. In a second aspect, the invention is directed to a closure latch that is movable to a safety locking position, wherein the inside and outside door levers are disabled and wherein the pawl is prevented from releasing the ratchet. The safety locking position may be used when the vehicle controller senses an impending crash or that a crash is occurring as a way of inhibiting inadvertent opening of the vehicle closure panel (eg. a vehicle door).

Abstract: A locking device is provided for preventing a motor vehicle door from opening when a handle portion of a handle assembly moves with acceleration above a predetermined threshold relative to a base thereof. The locking device includes a lock cup fixedly secured to the base and having a plurality of teeth. The locking device also includes a spool rotatably coupled to the lock cup and operably connected to the handle portion. The spool includes a pawl rotatably mounted thereto. The locking device further includes an inertia element disposed between the lock cup and the spool. The inertia element is coupled to the pawl such that upon the acceleration above the predetermined threshold the inertia element lags rotation of the spool and forces the pawl into engagement with one of the plurality of teeth to stop movement of the handle portion relative to the base and prevent the door from opening.

Abstract: A latch assembly selectively engages a striker for latching a door to a motor vehicle body. The latch assembly includes a housing. A ratchet is rotatably mounted to the housing for movement between an engaged position engaging the striker and a release position. A ratchet-engaging pawl is rotatably mounted to the housing and engageable with the ratchet to retain the ratchet in the engaged position. An inertia mechanism is operably connected to the ratchet-engaging pawl to prevent the ratchet-engaging pawl from pivoting out of engagement with the ratchet when the ratchet-engaging pawl begins to pivot due to inertial forces acting thereupon.

A ratchet is rotatably mounted to the housing for movement between an engaged position engaging the striker and a release position. A pawl is rotatably mounted to the housing and engageable with the ratchet to retain the ratchet in the engaged position. An inertia catch is coupled to the housing and is operably connected to the pawl for preventing the pawl from moving out of engagement with the ratchet in the event of a motor vehicle impact.

Abstract: A handle assembly selectively allows the door latch of a door of a motor vehicle to be released. The handle assembly includes a base fixedly secured to the door. The handle assembly also includes a handle portion and a lock trigger. The handle portion is operatively connected to a door latch mechanism effectuating the opening of the door. The lock trigger is movably engaged with the handle portion to allow or disallow the movement of the handle assembly and hence the opening of the door.
