  • Patent number: 10526817
    Abstract: A vehicle includes a door with an interior door cavity, as well as a lock rod and another item of a locking system, an impact beam, an attack member and a push member, all housed in the interior door cavity. The impact beam crosses the other item from laterally between the other item and the door. The attack member faces the lock rod from laterally between the door and the lock rod. The push member, along the impact beam, faces the other item from laterally between the other item and the door and laterally beyond the impact beam. When the door collapses when compromised by a side impact event, the door carries the attack member for attacking action on the lock rod. The door additionally carries the push member for counterpart pushing action on the other item. A connection between the lock rod and the other item thus breaks.

  • Publication number: 20180163437
    Abstract: A flush mounted handle assembly is provided for a power slide door of a vehicle. The handle assembly includes a case fixed to the door, the case defining a rear wall and opposing side portions. A bell crank is provided configured to coordinate selective power and manual operational modes of the assembly. The assembly includes a handle base having a first end and a second opposing end. The first and seconds ends are configured for selective pivotal movement in opposite directions about a fixed pivot axis to engage the bell crank. A pair of weighted paddles is provided, each rotatable about an axis independent from the handle base axis. One or more paddle biasing members is provided to bias the weighted paddles against the handle base, minimizing movement of the handle base in the manual operational mode upon an impact, or during an unintended rotational movement of the handle base.
