Abstract
A door checking apparatus for an automobile comprising an array of needle bearings held in contact with a bearing surface comprising axially oriented grooves, by means of a resilient energy storage device; a cylindrical cage coaxially adjacent the bearing surface and comprising an axially oriented array of slots arranged to retain the needle bearings; means to impart rotary motion to the cylindrical cage to cause the needle bearings to move relative to the bearing surface to create a torque reaction in response to deflection of the resilient energy storage device as the needle bearings move into and out of the grooves; means to transmit the imparted torque from the bearing surface into an appropriate structure.
