PCT No. PCT/CH88/00079 Sec. 371 Date Dec. 14, 1988 Sec. 102(e) Date Dec. 14, 1988 PCT Filed Apr. 14, 1988 PCT Pub. No. WO88/08060 PCT Pub. Date Oct. 20, 1988.In bearing structures which can be converted from a rest shape to an operational shape of larger volume and have at least one flat bearing part (1) and at least one support part (2) movable with and/or detachable therefrom, the problem consists in achieving good shape retention and in particular high resistance to bending without affecting the geometrical adaptability. The solution is achieved through three features: (a) the flat bearing part (1) is essentially resistant to bending in the first normal plane (NE1) and comparatively flexible in at least a second normal plane (NE2) at an angle to the first normal plane; (b) the bearing part (1) has an at least sectionally-curved functional shape; (c) when the bearing structure is in its operational shape the support part (2) is connected in a push-resistant manner with at least one region of the bearing part (1) which extends at an angle to the first normal plane (NE1). |
