Abstract: A torso support for a seat, having: a padding base 2; an outer link 3; an inner link 4; a U shaped clamp 6; a release button 5; a pivot pin 7; and a seat attachment bracket 8. The inner link 4 has a space housing the button 5. The button 5 can be pressed so it pivots between locking and unlocking dispositions. When in the locking disposition, the inner edge 13 of the button is close to a short arm of the clamp so they are almost abutting. This prevents the inner link 14 pivoting because to move in that way would cause a clash between the inner edge of the clamp 6 and the button 5.

Abstract: The invention provides a cushioning system having an adjustable contoured surface, the system comprising a panel, a plurality of cells; and attachment means for detachably attaching one or more cells to the panel at any location on the panel and in any orientation relative to the panel to provide the contoured surface. The contoured surface is determined by the number, shape, size, position, and orientation of cells on the panel. Optionally, the cells can be attached to each other and stackable upon one another.
