A power striker for door latch employed on the sliding side door of a van type vehicle includes a power driver rotary drive member which upon rotation through 180°is operable to drive a slide member in linear movement between opposite end limits. A striker pin may be mounted directly on the slide or coupled by linkage to the slide to be located in a ready position when the slide is at one end limit and in an actuated position when the slide is at its other end limit. When in its ready position, the pin is latched to the closing door before the door reaches its fully closed position. The pin is then driven to its actuated position to power the door to its fully closed position against the resistive force exerted by the compressible door seal. The rotary to linear drive coupling develops a sinusoidally increasing door closing force during the final door closing movement and provides a positive retention of the striker pin in its ready and actuated positions.

In a sliding door assembly including a fixed frame defining a door opening, a door mounted on said frame for sliding movement along a fixed door path between a first end limit wherein said door is located in a closed position closing said opening and a second end limit wherein said door is in an open position, a striker pin mounted on said fixed frame, and latch means mounted on said door engageable with said striker pin for releasably latching said door in said closed position, said latch means being operable during movement of said door toward said closed position to interlock with said striker pin to releasably latch said door against movement relative to said striker pin; the improvement comprising means mounting said striker pin for movement relative to said frame along a fixed pin path between a ready position and an actuated position, said pin when in said ready position being engageable by said latch means upon closing movement of said door to an approach position spaced from its closed position and being operable when in said actuated position to latch said door in its closed position, and means for driving said pin between said ready and closed positions comprising a first slide member mounted on said frame for sliding movement along a first fixed linear slide path, a second slide member carrying said striker pin for displacement along a second fixed linear slide path angularly offset from said first slide path, means interconnecting said slide members to effect synchronized displacement therebetween, a drive member mounted for rotation about a fixed axis normal to said first slide path, first coupling means coupling said drive member to said first slide member for transmitting that component of rotary motion of said first drive member which is parallel to said first slide path to said first slide member to move said first slide member along said first slide path between a first and a second rest position in response to a 180 degree rotation of said drive member about said axis, second coupling means coupling said pin to said second slide member for locating said pin in said ready position when said first slide member is in said first rest position and for locating said pin in said actuated position when said first slide member is in said second rest position, and actuating means operable in response to closing movement of said door past said approach position for rotating said drive member to drive said first slide member from said first rest position to said second rest position and operable in response to opening movement of said door past said approach position to rotate said drive member to drive said first slide member from said second position to said first position.
