Abstract:

A method of forming a seat cushion of a vehicle seat includes locating a motor in a first portion of a housing, and positioning a second portion of the housing on the first portion of the housing, wherein one of the first and second portion of the housing includes a meltable feature located near a location of contact of the first and second portion. The meltable feature is melted to permanently secure the first and second portion together and provide a sealed housing that retains and seals the motor. The sealed housing is suspended in a mold with a rod. Liquid foam is poured into the mold, and the liquid foam is allowed to solidify to form a solid foam seat cushion that encapsulates the sealed housing and embeds the sealed housing in the foam cushion. The sealed housing prevents the liquid foam from contacting the motor.
