Abstract: A modular and electromechanically integrated easy-entry mechanism includes an easy-entry mechanism, manufactured independently of slide rail assemblies, and mounted on upper slide rails in the slide rail assemblies by fasteners. A total travel of slide rails is divided into a comfort travel for front-rear adjustment of a passenger and an easy-entry travel for increasing an easy-entry/exit space for a passenger in the third row seating. The unlocking of the slide rails is mechanically maintained in the easy-entry travel, and the slide rails are ensured to be locked at the front-most position of the comfort travel when a seat is retracted. The easy-entry mechanism is driven manually or by electric power, and acts independently on unlocking pins in slide rail locking mechanisms to unlock the slide rail assemblies. The easy-entry mechanism is modularly designed, easy to manufacture, mount, and replace, and does not affect the existing slide rail manufacturing process.
