21st Century Scientific's Power Tilt System (PTS) can be installed on all BOUNDER models. With a power tilt system, the user can control the angle between the seat and the ground. The front of the seat tilts up from the normal driving position, and the seat and back move together. Usually the tilt can be adjusted over about a 45 degree range. The seat to back angle is fixed, usually at 94.5 degrees, though other seat to back angles can be custom ordered. The arms and front rigging move with the seat. Most styles of BOUNDER arms and front rigging can be installed on power tilt systems, including DIPLR dual independent power legrests. The PTS gives the user added independence and improved seating comfort.
Many users prefer a tilt system in combination with a power recliner, power seat elevator, and/or power legrests. See the combination system listings for more information.
The PTS is normally configured for a sheet metal pan seat. However, sling upholstery as well as other forms of solid seating are also available. Sling backs, solid backs and sheet metal pan backs can be installed on all PTS chairs.
HEADREST - PTS does not include a headrest. Since most users do require a headrest, be sure to order one if you need it. Many styles are available; adjustable center post headrests are the most popular.
STD TS PSS CTRL - Standard toggle switch control. Move the spring loaded center off toggle switch in one direction to tilt the seat up; move it in the other direction to return the seat to the normal driving position.
JOYSTICK PSS CTRL - Joystick Control of Power Seating System. Allows user to proportionally control up to six different actuators through the joystick. Speed and direction of movement are controlled by joystick position. Control is very smooth and actuator jerking is eliminated. A bi-directional select switch chooses which power seating function is being controlled by the joystick.
