Patent ID: 11931302

Abstract:
Optionally, a plurality of spacers 228 is arranged between the planar surface 120 of the interfacing arrangement 114 (or the top horizontal arm) and the seat arrangement 102, for permanently raising the seat arrangement 102 with respect to the interfacing arrangement 114. The spacers 228 can be implemented as rectangular or cylindrical solid blocks that can be fabricated from plastics materials, metals, metal alloys, polymers, ceramics, wood, composites and so forth. The spacers 228 can be fixed between the seat arrangement 102 and the top planar surface 120 of the top horizontal arm of the interfacing arrangement 114 such that height of the seat arrangement 102 relative to the footrest arrangement 116 is raised. For example, a plurality of metallic spacers is fixed between the seat arrangement 102 and the interface arrangement by a technician such as by welding the metallic spacers between the seat arrangement 102 and the interface arrangement. Such metallic spacers enable a height of the seat arrangement 102 to be customized with respect to the footrest arrangement 116, such as, when the height is required to be permanently adjusted for specifications (such as height) of the user.
