Rotary locking mechanism for outside vehicle door handle

A locking device for selectively preventing a fork rotatably mounted to a base from releasing a bolt upon movement of a door, said locking device comprising:

• a plurality of teeth fixedly secured to the base adjacent the fork;
• a pawl rotatably mounted to the fork and having an engaging portion, said pawl including a pawl pin extending out therefrom;
• and
• an inertia element rotatably coupled to said pawl, said inertia element including an elongated slot extending between a first end and a second end and receiving said pawl pin therewithin such that upon the acceleration of the door below a predetermined threshold said inertia element simultaneously rotates with the fork to allow the fork to release the bolt and upon the acceleration of the door above the predetermined threshold rotation of said inertia element lags behind rotation of the fork such that said pawl pin moves to the second end of said elongated slot to urge said engaging portion of said pawl into engagement with one of said plurality of teeth to prevent the fork from releasing the bolt.

A locking device for selectively preventing a motor vehicle door from opening upon movement of a main door latch, including a latch pawl and a ratchet, relative to a base, said locking device comprising:

• a plurality of teeth fixedly secured to the base;
• a pawl rotatably mounted to the latch pawl, said pawl including a pawl pin extending out therefrom;
• and
• an inertia element rotatably coupled to said pawl and including an elongated slot extending between first and second ends for receiving said pawl pin therewithin such that upon acceleration of the latch pawl below a predetermined threshold said inertia element rotates simultaneously with the latch pawl and the latch pawl releases the ratchet to allow opening of the door and upon acceleration of the latch pawl above the predetermined threshold said inertia element lags rotation of the latch pawl so that said pawl pin moves to said second end of said elongated slot and said pawl engages one of said plurality of teeth to stop movement of the latch pawl and prevent the door from opening.

A handle assembly for actuating a door latch mechanism of a motor vehicle door, said handle assembly comprising:

• a base adapted to be fixedly secured to the door;
• a handle portion pivotally secured to said base and operatively connected to the door latch mechanism;
• a lock cup fixedly secured to said base and having a plurality of teeth;
• a spool rotatably coupled to said lock cup and operably connected to said handle portion, said spool having a pawl rotatably mounted thereto, said pawl including a projection extending out therefrom;
• and
• an inertia element disposed between said spool and said lock cup, said inertia element including an elongated slot extending between first and second ends and receiving said pawl projection therewithin such that when said handle portion moves with acceleration below a predetermined threshold said inertia element rotates with said spool and said pawl remains spaced apart from said second end of said elongated slot such that the handle portion moves relative to the base and the door latch mechanism is released and when said handle portion moves with acceleration above the predetermined threshold said inertia element lags rotation of said spool and forces said pawl projection to said second end of said elongated slot in order to move said pawl into engagement with one of said plurality of teeth to stop movement of said handle portion relative to said base and prevent the door from opening.
