Abstract
A resilient linear latch and crash stop device incorporates a magnetic latch and a linear impact absorbing crash stop into a single composite body made up of a magnet member for contacting a strike plate on the actuator arm, an energy absorbing member, and a latch base body assembled together. The energy absorbing member fastens the magnet member to the base body and absorbs impact energy in a generally linear fashion throughout the range of anticipated impact magnitudes. The energy absorbing member is a generally rectangular elastomeric bellows member formed in place and sandwiched between the magnetic mounting plate and the base body. The elastomeric bellows member has a vertically open tubular passage therethrough that preferably has a bell shaped horizontal cross sectional shape.
