Patent ID: 7673419

Claim:
A rear window assembly for a vehicle comprising: a window frame; at least one fixed window panel having a least one perimeter edge defining a portion of an opening; a movable window panel capable of movement between a closed position which closes the opening and an open position which exposes the opening; wherein a surface of the movable window panel is allowed to slidably move past a surface of the fixed window panel in a substantially linear path; a seal member present on the perimeter surface of at least one window panel; at least one closure pin and one coil spring mounted with the movable window panel; and the window frame forming a closure track in at least one edge of the window frame and an indentation that can interact with the closure pin, the closure track having a bend that makes a predetermined departure angle (δ) from the linear path of the movable window panel and an inclined wall that connects the indentation to the closure track through a predetermined incline angle (φ 2 ), the predetermined incline angle (φ 2 ) being greater than 90°; the inclined wall cooperating with the closure pin, which is urged into contact with the inclined wall by the coil spring, to assist in moving the movable window panel towards the fixed window panel, thereby, urging the window assembly toward its closed position; wherein the closure track forces the movable window panel and the fixed window panel closer together placing the seal member under compression.
