Chair-drive interface assembly, wheelchair and/or drive

An apparatus for connection to, and use with, a wheelchair assembly having a first chair-connection member and a second chair-connection member spaced apart from the first chair-connection member, and the apparatus also for use with a drive assembly including a wheel assembly, a motor assembly, a drive-connection member and a steering assembly, in which the wheel assembly is configured to contact a working surface, and the motor assembly is configured to couple to the wheel assembly, and the motor assembly is also configured to rotate the wheel assembly, and the steering assembly is configured to couple to the wheel assembly, and is configured to steer the wheel assembly, the apparatus comprising:

• a chair-drive interface assembly including:
• a first connection member configured to be fixedly attached to the first chair-connection member;
• and
• a second connection member configured to be fixedly attached to the second chair-connection member, and in which the second connection member is spaced apart from the first connection member;
• and
• a third connection member configured to be fixedly attached to the drive-connection member of the drive assembly, in which the third connection member is spaced apart from the second connection member and from the first connection member.

An apparatus, comprising:

• a wheelchair assembly having a first chair-connection member and a second chair-connection member spaced apart from the first chair-connection member;
• and
• a drive assembly including a wheel assembly, a motor assembly and a steering assembly, in which the wheel assembly is configured to contact a working surface, and in which the motor assembly is configured to couple to the wheel assembly, and is also configured to rotate the wheel assembly, and in which the steering assembly is configured to couple to the wheel assembly, and is configured to steer the wheel assembly;
• and
• a chair-drive interface assembly having a first connection member configured to be fixedly attached to the first chair-connection member;
• and
• the chair-drive interface assembly also having a second connection member configured to be fixedly attached to the second chair-connection member, in which the second connection member is spaced apart from the first connection member;
• and
• the chair-drive interface assembly also having a third connection member configured to be fixedly attached to the drive assembly, in which the third connection member is spaced apart from the second connection member and from the first connection member;
• and
• the first connection member and the second connection member, of the chair-drive interface assembly, are configured to promote, at least in part, transmission of a movement force from the drive assembly across the first chair-connection member and the second chair-connection member of the wheelchair assembly;
• and
• the first connection member and the second connection member and the third connection member, of the chair-drive interface assembly are also configured to prevent, at least in part, the drive assembly from imparting, at least in part, a force that structurally weakens, at least in part, the chair-drive interface assembly or structurally weakens, at least in part, the wheelchair assembly.
