OccuForm Hard Shell
The OccuForm Hard Shell consists of a fiberglass seat pan and fiberglass seat back connected by a weighted mechanical linkage. Seatback contour derived from UMTRI Shells Model Data. Seat pan contour developed from merging ASPECT contour surface data with UMTRI Shells model. Size and contours match ASPECT (SAE J826) 50th Percentile Male.
The OccuForm Hard Shell was a cooperative development of Humanetics and Lear Corporation. Lear Corporation uses the OccuForm Hard Shell for the majority of its seat testing programs.
