  • Patent number: 9273497
    Abstract: A motor vehicle door latch includes a rotary latch which encompasses a closing element when in the closed position, and is preloaded toward an open position of the closing element. A safety catch is engaged with the rotary latch so that the rotary latch is prevented from moving toward the open position. A coupling section of the safety catch is dynamically coupled with a drive element and moves the safety catch between the engagement position and a releasing position so that the rotary latch can move toward the open position. The opening sound is reduced to a minimum. The drive element moves the safety catch from the engagement position toward the releasing position so that the rotary latch, which is still engaged with the safety catch during such movement, moves toward the open position.

  • Patent number: 5342123
    Abstract: A door forming a part of a closure assembly is attached to the frame of the closure assembly by engaging bifurcated branches of a pivot arm with a pivot shaft. One of the branches is extended to engage a curved leaf spring which is deformed as the door and the extension is pivoted about the shaft. The deformation of the spring is instrumental in exerting a force on the extension to detent the door in the closed position and the extension may disengage from the spring surface when in the open position. To further stabilize the door, a stabilizer is formed on the back of the door and it engages the end of a recessed channel in the assembly, at a point coincident with the pivot axis of the door.
