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.

Abstract: A sliding rail having an enhanced rigidity modulus including an upper rail assembly, a lower rail assembly, and retainers is provided. The upper rail assembly is slidably arranged in a sliding groove in the lower rail assembly through a pair of retainers. First raised ribs and/or steel ball clamping grooves are arranged at intervals on surfaces of the retainers. A steel ball is mounted in the steel ball clamping groove. A supporting structure extending backwards in a length direction of the retainers is arranged at a rear end of each of the retainers. When the upper rail assembly slides backwards to the farthest stroke, the supporting structure provides longitudinal auxiliary support for a mid-rear section of the upper rail assembly, the supporting structure is in contact with the lower rail assembly, and a gap is reserved between the supporting structure and the upper rail assembly.
