DESCRIPTION:
BRIEF SUMMARY
My invention pertains to a one-piece seat shell having a backrest and a seat connected by a curved transition section.
SUMMARY OF THE INVENTION
My invention pertains to a one-piece seat shell having a backrest and a seat connected by a curved transition section that permits resilient deflection of the backrest with respect to the seat.
BRIEF DESCRIPTION OF THE DRAWING
The drawing is a perspective view of the one-piece seat shell.
DESCRIPTION
The drawing shows a seat shell 10 made of rigid basic material (for example plywood) having a backrest 12, a seat 14 and an angled transition region 16 connecting the two. A plurality of slots 18' are provided in the transition region 16 and optionally also in the adjacent region of the backrest 12 and the seat 14. Slots 18' extend in the transverse direction and extend parallel to each other. Some slots may be inclined at a slight angle, in the manner of a pencil of rays. The slots 18' facilitate a resilient deflection of the backrest 12 with respect to the seat 14.
The area indicated by broken lines 20' defines the region 22 of the seat shell which is subject to spring action or resilient deflection. The slots can be covered by easily cut coverings.
1. A one piece seat shell (10) comprising the backrest (12) and the seat (14), a laterally exterior edge of said transition section (16), the slots (18') in each group between them an intermediate transition region (22) of the seat shell (10) transition region (22) both outwardly towards said backrest (12) and outwardly towards said seat (14).
