ABSTRACT:
In the reclining apparatus of the invention(1, 21, 41, 61), the support member(2, 22, 42, 62), the seat member(3, 23, 43, 63) and the back rest member(5, 25, 45, 55, 75) are adjustably interconnected and the rod(11, 31, 51, 71) of the lock device(13, 33, 53, 73) is mounted on one of the support member, the seat member and the back rest member and fitted across another one of them. When a force is applied between the rod and the member through which the rod is fitted, all the positions of the above members are maintained.
When a person changes the posture, e.g., stretches himself, on the reclining chair(1, 21, 61) or the reclinable bed(41), the lock between the rod and the member through which the rod is fitted is released and the positions of the support member, the seat member and the back rest member are re-adjusted. After the re-adjustment, when the person seats or lies on the chair or the bed, the rod is again firmly engaged with the member.
