<P>PROBLEM TO BE SOLVED: To improve a getting-out property as compared with a conventional one by dissolving projection of a side support portion of a vehicular seat. <P>SOLUTION: In the support portion variable structure, a pressing portion 34 is separated from a seat including element 26 with opening action of a rear door 30 when the rear door 30 is opened while an occupant is seated in a rear seat 14. Therefore, a pressing state by the pressing portion 34 of a locker including element 20 is released, and fluid moves from the seat including element 26 to the locker including element 20 through a coupling tube 28. In such a way, when the fluid in the seat including element 26 is moved to the locker including element 20, the seat including element 26 shrinks by fluid movement to the locker including element 20. Therefore, projecting amount from a seat surface center portion 36 of the side support portion 24 is reduced to β (α>β). Consequently, it is suppressed that the side support portion 24 obstructs getting-out, and the getting-out property can be improved as compared with a conventional one. <P>COPYRIGHT: (C)2008,JPO&INPIT |
