ABSTRACT:
The combination 10 of a foot restraint platform 12 designed primarily for use by an astronaut being rigidly and permanently attached to an end effector 14 which is suitable for attachment to the manipulator arm 16 of a remote manipulating system. The foot restraint platform, is attached by a brace 36 to the end effector 14 at a location away from the grappling interface of the end effector. The platform comprises a support plate 18 provided with a pair of stirrups 21,22 for receiving the toe portion of an astronaut's boots when standing on the platform and a pair of heel retainers 23,24 in the form of raised members which are fixed to the surface of the platform and located to provide abutment surfaces for abutting engagement with the heels of the astronaut's boots when his toes are in the stirrups. The heel retainers 23,24 preclude a backward sliding movement of the feet on the platform and instead require a lifting of the heels in order to extract the feet. The brace 36 for attaching the foot restraint platform to the end effector may include a pivot or swivel joint to permit various orientations of the platform with respect to the end effector.
