Motor vehicle egress window

A motor vehicle egress window comprising, in combination:

• a. an outer frame forming an auxiliary egress opening for a motor vehicle passenger compartment, the egress opening having a horizontal upper portion and a horizontal lower portion, each being straight and parallel with one another, and a vertical left side portion and a vertical right side portion, each being straight and parallel with one another, wherein the outer frame comprises
• i. a one-piece outer frame member having a continuous inner surface extending circumferentially along at least the vertical left side portion, horizontal lower portion and vertical right side portion,
• ii. multiple striker pins mounted directly to the outer frame member along the horizontal lower portion and oriented to extend radially inwardly from the molded inner surface, and
• iii. an upwardly open outer frame hinge hook extending along the horizontal upper frame portion;
• and
• b. an inner frame unit hingedly mounted to the outer frame for movement between a closed position in which it closes the auxiliary egress opening formed by the outer frame and an open position, comprising
• i. a one-piece inner frame member having a circumferentially continuous molded surface configured to mate with a corresponding portion of the inner surface of the outer frame member when the inner frame is in the closed position,
• ii. at least one glazing pane mounted in the inner frame,
• iii. multiple rotary slam latches, each mounted to a horizontal lower portion of the inner frame member and operative when the inner frame is in the closed position to latch to a corresponding one of the striker pins of the outer frame to releasably hold the inner frame unit in the closed position,
• iv. a release mechanism comprising
• a manually operative release handle mounted to a vertical side portion of the inner frame, and
• release linkage comprising
• a flexible cable extending in a circumferentially extending rail of the inner frame at least from the release handle to a first one of the rotary slam latches mounted to the horizontal lower portion of the inner frame, and
• a rigid link member extending from the first one of the rotary slam latches to a second of the of the rotary slam latches,
• the release mechanism being operative upon operation of the release handle to simultaneously unlatch the multiple rotary slam latches to release the striker pins to free the inner frame unit to move to the open position, and
• v. a downwardly open inner frame hinge hook extending from the inner frame member along an upper horizontal portion of the inner frame member and received by the outer frame hinge hook.
