Multi-function mobility device
First Claim
1. A mobility device capable of being configured in a plurality of configurations, comprising:
- a lower structure including a chassis shell having lower floor and rear closing transverse areas connecting opposed sidewalls and a front suspension arm mount assembly and a rear suspension arm mount assembly;
each of said suspension arm mount assemblies having a suspension arm mount for receiving a suspension arm;
said suspension arm having a connecting portion and a wheel coupling portion, said connecting portion adapted to be connectable and removable with one of said suspension arm mounts and said wheel coupling portion configured to be coupled with a wheel/tire assembly;
an upper occupant shell structure assembly; and
a pivot connector for coupling/decoupling said upper occupant shell structure assembly with/from said chassis shell, said pivot connector allowing for position adjustment of at least one of said shells about an axis of rotation such that said shells can be positioned in the desired configuration.

Abstract
A multi-function stroller may comprise a lower chassis shell and an upper occupant shell connected by a quick release pivot joint that provides occupant accommodation that is secure and comfortable. In addition, the structural architecture is designed to allow safe adaptations to the axle configuration. Through flexible suspension arm mounting the suspension-hub-wheel/tire assembly can be quickly assembled/disassembled to provide alternative usage axle layouts. An ergonomic handle assembly may be coupled with the structure for pushing, pulling, towing, carrying, etc. When disassembled, the multi-function stroller can be folded into a compact storage mode. Thus, non-compromised performance, versatility, and usage functionality can be readily achieved and accomplished in a safe manner.
