Abstract
A containment device is described which has been developed for use on stairlift chairs, but may have a variety of other applications. The containment device includes a belt (26) retractably wound onto a reel. The reel is, in turn, mounted in a carrier (28). In operation, the carrier (28) is displaced to a locking point, the act of displacement unwinding the belt from the reel. When the carrier (28) is locked in position the belt (26) is locked with respect to the reel. Other features, particularly relevant to stairlift applications, are described.
Claims23
A containment device including a reel mounted for rotation in a reel carrier;
- a length of web wound onto, and fixed at one end to, said reel and having an opposite free end, said restraint being characterized in that said free end is, in use, fixed to an installation, said reel carrier being displaceable from the fixing point of said free end to unwind said web.
A stairlift chair having a pair of spaced armrests and a containment device operable to, in use, retain a stairlift user within said chair, said chair being characterized in that part of said containment is mounted on one of said armrests, and part of said containment device, in use, removeably engages with the other of said armrests.
A stairlift chair having a containment device, said containment device including a belt wound on a reel and being extendible between a retracted configuration in which said containment device does not inhibit movement of a user into or out of said chair, and an extended position in which said containment inhibits the movement of said user from said chair, said containment device being characterized in that the act of fixing said containment device in said extended position fixes said belt with respect to said reel.
A stairlift chair having a containment device, said containment device having a fixing component;
- a reel carrier displaceable toward, and engageable with, said fixing component;
- a reel rotatably mounted within said reel carrier;
- a first belt fixed to said reel for winding on to, and from, said reel;
- and a second belt fixed at one end to said chair and at the other end to said reel carrier, one of said first and second belts being configured to pass over the lap of a user and the other of said first and second belts being configured to pass over a shoulder of a user.
