A movement device including a rigid inner supporting rod-like member of a closed circuit configuration and a flexible, closed sleeve slidably mounted on the rod-like support member. In one application of the invention, a drawer or the like can be moved relative to a case or the like by securing the drawer to the sleeve and securing the case to the sleeve at points on opposite sides of a point at which the rod-like support member changes direction. In another application, the device is used as a tilting mechanism for chairs by securing the chair body to the sleeve and securing the chair base to the sleeve at points opposite a point at which the rod-like member changes direction. The chair base can be eliminated by setting the rigid rod-like member directly on the floor. The device also provides a rotatable base for a stool. In another application, the device is used as a bearing between a shaft and a bearing sleeve, the shaft frictionally engaging the flexible sleeve on the inside of the closed circuit and the bearing sleeve frictionally engaging the flexible sleeve on the outside of the closed circuit configuration. In another application, the device is used as a drive pulley by supportably engaging the flexible sleeve by several pulley wheels at two spaced points whereby the rotation of one pulley wheel causes the sleeve to slide on the rigid rod-like member and rotates the other pulley wheels.

This is a divisional application of parent application Ser. No. 310,411, filed Nov. 29, 1972, now U.S. Pat. No. 3,883,192, and entitled MOVEMENT DEVICE.
In order to make an apparatus for attenuating the pivotal or sliding movement of motor-vehicle parts which is formed of a first part fixed on the nonsliding or nonpivoting part and a second part mounted on the pivotal or slidable part which is extremely inexpensive and which takes up minimal space it is suggested that one of the two elements be formed by a tubular and stiff or flexible tube which is filled with a viscous mass and that the other part being formed by a core which slides in the tubular body so that relative pivoting or sliding of the parts coaxially slides the core relative to the tubular body.
