摘要:
A collar with a relieved area (3) strategically placed in-between the upper and lower wheelchair leg-rest attachments (2) so a leg-rest can still be removed and installed and where the leg-rest locking arm (6) can lock into place unimpeded. A second collar (4) attached directly below the lower wheelchair leg-rest attachment (2). Both collars (3 and 4) are locked into place using flat-head screws (5). Collars (3 and 4) are of sufficient size to extend horizontally beyond the typically exposed mainframe leg-rest attachments (2). When installed at both leg-rest attachment areas (2) the invention protects a wheelchair user from a laceration injury.
