Abstract

A shape adjusting mechanism is provided having a basket that is flexed on a guide track by a cable mechanism. The basket comprises an elongate resilient plate in which is defined at least one slot. The slot has at least one reinforcing flange that defines a region of high bending resistance relative to a controlled arch region in the plate in order that the flex of the plate in the controlled region will be more pronounced than in the region with the slot. A reinforcing edge flange is also provided along at least a portion of the longitudinal edge of the plate. In a further embodiment a plurality of crossforms are defined transversely in the controlled arch region to predefi ne an arch in the plate while the plate is in a rest state.
