Reverse Tilt on BOUNDER Plus with Recaro Leather seat
Reverse Power Tilt System (RPTS) on BOUNDER Plus with Recaro Seating

21st Century Scientific's Reverse Power Tilt System (RPTS) can be installed on all BOUNDER models. With a reverse power tilt system, the user can control the angle between the seat and the ground. The back of the seat tilts up from the normal driving position, and the seat and back move together. This allows for easier transfers into and out of the chair from a standing position. Toggle switch control is standard. Usually the tilt can be adjusted over about a 30 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 move with the seat. Front rigging is attached to the base of the chair and do not move with the seat. Most styles of BOUNDER arms and front rigging can be installed on reverse power tilt systems, including DIPLR dual independent power elevating legrests.

Many users prefer a Reverse Power Tilt System in combination with a power recliner, power seat elevator, and/or power legrests. See the combination system listings for more information.


HEADREST - RPTS 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.

JS & TS TILT CTRL - Joystick and Toggle Switch Control of Reverse Tilt. Toggle switch is usually placed near the rear of the left or right arm to facilitate return to upright position when back is fully tilted.

TILT LO - Power Tilt System Lockout (prevents chair from moving when seat is tilted)

PSS HD - Power Seating System Heavy Duty Upgrade (for users between 250 and 400 lbs). Sometimes the amount of tilt is limited.

PSS XHD - Power Seating System Xtra Heavy Duty Upgrade (for users above 400 lbs). Usually the amount of tilt is limited to 30 degrees.
