Abstract
Abstract A motor vehicle door latch has an inner plate which is secured to the inner face of the edge panel of the vehicle door and on which is secured the operating mechanism of the latch. An outer housing has a metal plate and a synthetic-resin body spacing the plate from the edge panel with the locking pawl and other mechansim for engaging and holding the bolt on the doorpost. Screws secure the two plates together and pass through the door-edge panel and the synthetic-resin body, acting as pivot axes for the pawl and other rotary mechanism in the outer housing. The body is formed with tubular regions on which the rotary elements such as the locking pawl are pivoted and through which the screws pass as reinforcement.
