DUAL TRACK EZ-ENTRY SYSTEM FOR SECOND ROW VEHICLE SEAT

ABSTRACT

         A dual track EZ-entry second row seat provides a maximum ingress/egress gap for entry and exit of a vehicle, and one-hand operation of the mechanism.

DISCUSSION

         This disclosure related to vehicle seats, and more particularly to a dual track, EZ- Entry System for stadium seating in the second row seats of a vehicle such as a van or sports utility vehicle.

         Typical seats for the second row of a vehicle requires that one or both of the second row seats move to provide ingress and egress to the cargo area behind such seats or to a third row of seats. Typical configuration for the second row provides for a tilting of the back end of the cushion up while lowering the front end as low as possible to the floor of the vehicle. Moving the back of the seat forward to close the gap between the back of the seat and the tilted up cushion thereby stacking the back and cushion of the second row seat as close as possible to the back of the front row seat.

         The tilting of the cushion is achieved by releasing cushion latches. A spring may be used to tilt the back of the cushion upwards. A cable pulley system can also be used to control the deployment and to reverse the action when the seat is to be replaced back to its design seating position.

         The forward movement of the seat back towards the upward tilting cushion is typically achieved by a 4-bar linkage system called a bunny-hop mechanism. In operation, a set of floor latches at the back of the seat are released and the seat weight is tilted forward with the help of assist springs.

         Known systems for affecting the above described movement is (1) a "track-on- track system" and (2) a "single track-dual carriage" system. However, such systems are limited by limited track length and small carriage spans in order to achieve the travel needed for the EZ- Entry movement.

         Thus there is a need for a dual track EZ-Entry system that is cost effective and can be operated by one hand of the operator and provides the ingress/egress gap for easy entry to or from the vehicle.

         As illustrated in the accompanying figures, the EZ-Entry system is accomplished by the use of a pair of parallel tracks coupled to the floor of the vehicle. The shorter track is hereinafter referred to as the "cushion track" and the longer track is hereinafter referred to as the "back frame track." (See Fig. 1.) In operation, the cushion is flipped such that the front of the cushion is pointed to the floor of the vehicle and the bite line of the cushion is pointed to the roof of the vehicle. (See Fig. 2.) The front portion of the cushion is attached to the cushion track and
