An object of the present invention is to provide a position holding pad Positions holding function the rear shift less stable is obtained. in An elastic material in Positions holding pad, which is formed in a substantially pillow-shaped, of the support surface 11 and the straight line and the intersection of the bottom of the bottom 14 14 which is substantially perpendicular to the tangent at the ridge portion of the top surface 12 together is positioned above the front end edge 14a nearer than the rear end edge 14b, the rear 13 that is positioned at a front edge 14a nearer than the rear end edge 14b of the bottom surface 14, body pressure exerted on the supporting surface 11 the majority is directed to the bottom 14 side, along with the work as a pressing force from the bottom surface 14 to the bed side, the back 13 part Seridasu from the rear end portion 14b of the bottom 14 to the rear side is suppressed as much as possible, these by both of the synergistic effect, Positions holding pad 1 is prevented as much as possible to the rear shift, with a position holding function the rear shift less stable.FIELD 1【課題】後方ズレが少なく安定した体位保持機能が得られる体位保持パッドを提供する。【解決手段】弾性材で略枕状に形成される体位保持パッドにおいて、支持面11と頂面12の稜線部における接線に略直交する直線と底面14との交点を底面14の後端縁14bよりも上記前端縁14a寄りに位置させるとともに、上記背面13を上記底面14の後端縁14bよりも前端縁14a寄りに位置させていることから、支持面11に掛る体圧はその大部分が底面14側に指向し、底面14から寝床側に押圧力として働くとともに、背面13部分が底面14の後端部14bから後方側へ迫り出すのが可及的に抑制され、これら両者の相乗効果により、体位保持パッド1が後方ズレするのが可及的に防止され、後方ズレが少なく安定した体位保持機能を持つ。【選択図】図1
