Flex Mat - Description

DESCRIPTION





Vehicles equipped with the Occupant Classification System (OCS) have a Flex Mat (3) in the passenger seat. The flex mat is sandwiched between the seat cushion springs and seat cushion foam. A heavy jute-like insulator pad is installed between the lower surface of the flex mat and the seat cushion springs. The flex mat is secured to the seat cushion frame by two plastic push-in fasteners (1) at the front edge of the seat cushion frame. The seat cushion foam is installed loosely over the top of the flex mat, then secured by the installation of the trim cover to the seat cushion. The flex mat is connected to the Occupant Classification Module (OCM) by one electrical connector (2).










The bladder (4) consists of two rectangular sheets of an elastomeric material. The two sheets of material are sealed together around their perimeter and heat staked to each other at numerous regular points within their field. Then the bladder is filled with a silicone fluid to become a pliable, quilted membrane.

The flex sensor is flat membrane contained within a molded plastic sheet with an integral electrical connector receptacle. The flex sensor connector contains terminal pins that connect the sensor to the vehicle electrical system and the OCM through a dedicated take out and connector of the passenger seat wire harness.

The flex mat cannot be adjusted or repaired. If found faulty or damaged, then the entire flex mat assembly must be replaced.

WARNING: When replacing the flex mat, the OCM Rezero procedure must be performed Testing and Inspection .
