Caster wheel support assembly for a wheelchair and wheelchair comprising the same

A caster wheel support assembly for a wheelchair, the caster wheel support assembly having a first section configured to be securable to a frame member of the wheelchair and a second section configured to hold a swivel member coupled to a caster wheel,

• wherein the caster wheel support assembly comprises a holding member designed as a collet configured to hold a first portion of the swivel member, wherein the first portion extends along a first axis,
• wherein a second portion of the swivel member, which is coupled to the caster wheel, extends away from the first portion along a second axis, wherein the second axis forms an angle relative to the first axis,
• wherein the holding member and swivel member are configured such that the first portion of the swivel member is supported by the holding member to selectively allow rotation of the swivel member relative to the holding member about the first axis and thereby cause adjustment of a camber of the caster wheel,
• wherein the collet is configured to selectively allow:
• clamping of the swivel member onto the holding member, thereby preventing rotation of the swivel member relative to the holding member;
• and
• release of the swivel member with respect to the holding member, thereby permitting rotation of the swivel member relative to the holding member,
• and wherein the first portion of the swivel member comprises a head portion that is designed to allow manual rotation of the swivel member about the first axis by means of a tool.
