Abstract
The invention relates to a motor vehicle door lock with a locking mechanism comprising a rotary latch and a pawl, a trigger lever which acts on the pawl, a blocking lever which acts on the trigger lever, a first actuating lever which acts on the trigger lever and which acts on the blocking lever via a first leg spring, and a second actuating lever which acts on the trigger lever and which acts on the blocking lever via a second leg spring.
Claims17
A motor vehicle door latch that resists opening in the event of an impact caused by the accident, the motor vehicle door latch comprising:
- a catch having a closed position;
- a pawl operable to hold the catch in the closed position;
- a triggering lever operable to move the pawl;
- a blocking lever operable to hold the triggering lever in a position where the triggering lever cannot move the pawl, wherein the blocking lever has a mass having a mass inertia that resists movement of the blocking lever;
- a first activation lever operably connected to a first handle and operably connected to the triggering lever;
- a first leg spring operatively connecting the first activation lever to the blocking lever, wherein the first leg spring creates a first delay between movement of the first activation lever and movement of the blocking lever, wherein the first delay is longer than a first duration of movement of the first activation lever caused by the impact, and wherein, after the first delay, the first leg spring moves the blocking lever out of the position where the triggering lever cannot move the pawl;
- a second activation lever operably connected to a second handle and operably connected to the triggering lever;
- and
- a second leg spring operatively connecting the second activation lever to the blocking lever, wherein the second leg spring creates a second delay between movement of the second activation lever and movement of the blocking lever, wherein the second delay is longer than a second duration of movement of the second activation lever caused by the impact, and wherein, after the second delay, the second leg spring moves the blocking lever out of the position where the triggering lever cannot move the pawl.
