They also promote upper-body strength and cardiovascular health. Wheelchair suspension helps to cushion sharp shocks, such as drops from thresholds or curbs and reduce the amount of vibration transmitted to the MWU. In-wheel suspension systems are a promising alternative to front caster suspension. Seat to Floor Height The height of the seat to the floor of a chair is vital because it determines the chair's ability to move across different surfaces. Wheelchairs usually have a smooth surface on the bottom that allows them to move across paved roads, sidewalks and even indoor surfaces like hardwood floors or tile. However, when you are moving outdoors on more rugged terrain the wheelchair needs to have a more robust tread that will enable it to be more stable on the ground. A suspension system is fitted on the frame of the chair to provide a smooth ride. A shock assembly is utilized to displace and absorb energy from the frame whenever it comes across uneven or rough surfaces. The shock assembly consists of springs that are connected to the chassis assembly and can be adjusted to alter how much energy is transferred from front to back or in reverse. A way to adjust the shock assembly is with a pin 1201 that can be inserted into one of several holes 1102 that are equally spaced. By changing the position of the pin 1201 allows you to make your wheelchair more rigid or soft in its ride by altering the amount of movement inside the shock assembly. In addition to the shock assembly forward wheels are attached to the chassis. These wheels are also adjustable and can be positioned in different positions to vary the amount of weight transferred from one side to the other. This allows the wh
