Abstract

An inflatable walking cushion 10 comprises a plurality of chambers 11 of gas-tight material attached to one another and communicating with one another by means of a main connecting line 14 so as to permit pressure equalisation between the chambers, and means 13 for securing the cushion 10 to the foot of the user. The stability of the walking cushion 10 is intended to be improved and its usefulness in the event of damage to one chamber 11 should be maintained at least for a certain length of time. For this purpose each chamber 11 is connected to the main connecting line 14 by means of at least two tie lines 15, each tie line containing a non-return valve 19a, 19b, and each non-return valve acting in a different direction from the other.
