Abstract
A seat for a mobility device accommodating flexibility, personalized comfort, and transportability. The seat can include a button push means to enable movement of a height-adjustable armrest. The seat back can fold upon the seat for transportability. The seat cushion and armrest cushion can be removably mounted and separately replaceable. The seat can be mounted upon various types of devices, including, but not limited to, wheelchairs.

A method for building a seat for a mobility device, the seat including a footrest, a bracket, at least one arm, a seat shell, and a back rest, the method comprising:
- pivotally connecting the footrest to a rod, the rod having a rod first end and a rod second end, the footrest including a first pivot means at the connection between the footrest and the rod first end;
- sliding, to adjust the footrest to a desired height, the rod second end into a receiving port of a hollow tube, the hollow tube including a connection port, the connection port including a compliant bumper, the compliant bumper buffering an effect of pressure on the rod and the hollow tube;
- pivotally connecting the connection port to the bracket, the bracket including seat shell alignment features, the bracket including at least one mobility device connection feature;
- operably connecting the seat shell to the seat shell alignment features and the bracket;
- pivotally connecting the back rest to the bracket, the back rest including a third pivot means, the third pivot means enabled by a spring-loaded latch;
- operably connecting at least one arm rest mount to the bracket, the at least one arm rest mount including a height adjustment means;
- and
- pivotally connecting the at least one arm to the at least one arm rest mount.
A method for transporting a seat of a mobility device, the seat including a footrest, a bracket, at least one arm rest, a seat shell, and a back rest, the method comprising:
- pivoting the footrest towards a rod connected to the footrest until the footrest is approximately flush with the rod, the rod having a rod first end and a rod second end, the footrest including a first pivot means at the connection between the footrest and the rod first end;
- sliding the rod second end into a receiving port of a hollow tube, the hollow tube including a connection port, the connection port including a second pivot means;
- pivoting the hollow tube at the connection port towards the bracket until the hollow tube is approximately flush with the bracket;
- pivoting the back rest towards the bracket at a third pivot means, the third pivot means enabled by a spring-loaded latch;
- reducing the height of the at least one arm rest mount by adjusting a height adjustment means;
- and
- pivoting the at least one arm rest towards the at least one arm rest mount until the at least one arm rest is flush with the at least one arm rest mount.
A seat assembly for a mobility device, the seat including a backrest, a seat pan, and an armrest, the seat assembly comprising:
- a back frame bracket enabling coupling with the backrest;
- a tube holder bracket enabling coupling with the seatpan;
- an armrest bracket enabling coupling with the armrest;
- and
- a cane, the cane being surrounded by the armrest bracket, the cane enabling adjustment of the armrest bracket, the cane enabling coupling between the back frame bracket and the tube holder bracket,
- wherein the armrest bracket comprises:
- a cane cavity receiving the cane, the cane including a plurality of set cavities;
- at least one fastener cavity;
- and
- an armrest geometry accommodating bracket geometry in the armrest, the armrest geometry and the bracket geometry enabling movement of the armrest.
A seat assembly for a mobility device, the seat including a backrest assembly, a seat pan, an armrest, and an attendant handle, the seat assembly comprising:
- a back frame bracket enabling coupling with the backrest, the back frame bracket;
- an attendant handle operating mechanism enabling movement of the attendant handle, the attendant handle operating mechanism including:
- at least one attendant handle stopper in contact with the attendant handle;
- a first beam having a first beam first end and a first beam second end, the first beam second end being movably coupled with one of the at least one attendant handle stoppers;
- a second beam having a second beam first end and a second beam second end, the second beam second end being movably coupled with one of the at least one attendant handle stoppers;
- and
- a central beam having a central beam first end and a central beam second end, the central beam first end movably coupling the first beam first end and the second beam first end, movement of the attendant handle being based at least on movement of the central beam;
- a tube holder bracket enabling coupling with the seatpan;
- an armrest bracket enabling coupling with the armrest;
- and
- a cane, the cane being surrounded by the armrest bracket, the cane enabling adjustment of the armrest bracket, the cane enabling coupling between the back frame bracket and the tube holder bracket.
