A vehicle seat side frame connects to a base via a force limiter part that undergoes plastic deformation under tensile load.
Undulating flexible suspension members adapt to passenger weight, resolving rigid support trade-offs in vehicle seatbacks.
Segmented U-shaped borders with perpendicular ribs resolve strength versus complexity contradictions by managing tensile stresses during rear crash impacts.
A vehicle backrest structure uses a driver plate and lever element to automatically unlock the inner seat part during outer backrest folding.
Tear-away stitches separate webbing straps under threshold loads to extend strap length and absorb impact energy.
