Abstract
Official abstract text for this publication.
A seat cushion adjusting apparatus includes: a nut support mechanism that supports a nut member on a frame of a seat cushion; and a variable mechanism that changes a length of the seat cushion based on an axial movement of a screw shaft screwed to the nut member, wherein the nut support mechanism allows the nut member and the screw shaft to be integrally tilted while restricting rotation of the nut member.
First claim
Opening claim text (preview).
What is claimed is: 1 . A seat cushion adjusting apparatus comprising: a nut support mechanism that supports a nut member on a frame of a seat cushion; and a variable mechanism that changes a length of the seat cushion based on an axial movement of a screw shaft screwed to the nut member, wherein the nut support mechanism allows the nut member and the screw shaft to be integrally tilted while restricting rotation of the nut member. 2 . The seat cushion adjusting apparatus according to claim 1 , wherein the nut support mechanism interposes the nut member between a pair of support walls disposed to face each other in an axial direction of the screw shaft, and wherein curved surfaces, which are convex toward the support walls facing end portions of the nut member in the axial direction, are formed in the end portions in the axial direction. 3 . The seat cushion adjusting apparatus according to claim 1 , wherein the nut support mechanism includes a pair of support walls provided in positions interposing the nut member in a seat width direction, and wherein the nut member has a rotation axis crossing both the support walls in the seat width direction. 4 . The seat cushion adjusting apparatus according to claim 3 , wherein long holes extending in a vertical direction are formed in both the support walls in the seat width direction and the rotation axis of the nut member is formed by a shaft-like member inserted through the long holes. 5 . The seat cushion adjusting apparatus according to claim 2 , wherein a holder member capable of elastically deforming is interposed between the support wall and the nut member. 6 . The seat cushion adjusting apparatus according to claim 5 , wherein the holder member is made of resin. 7 . The seat cushion adjusting apparatus according to claim 5 , wherein the holder member has the curved surfaces and is integrally tilted with the screw shaft and the nut member. 8 . The seat cushion adjusting apparatus according to claim 5 , wherein the holder member has the rotation axis and is integrally tilted with the screw shaft and the nut member.
