Adjust Etac Prio to Posterior Pelvic Tilt

A posterior pelvic tilt is often combined with tight Hamstrings which further complicates achieving a stable and supported position.

Back Support: The 3D (1) adapts perfectly and allow space for a curved back. Adjust the Dynamic Pelvic Support (2) and the tension adjustable back straps (3) to a comfortable and supportive position. Do this adjustment in the active position, so the dynamic pelvic support tension will deactivate in the resting position. Cell Foam Wedges (4) and/or Plush Wedges provide lateral stability. 

Seat to back angle: If the pelvis has a fixed posterior tilt, the active seat to back angle has to be secured. Ensure that the user has back support contact from the PSIS. Use the Back Angle Control (5) to secure this position. A contoured seat cushion (6) and a Positioning Belt (7) can provide further proximal stability and prevent forward sliding. Head Support: The Multi-Adjustable model (8) is the best choice since a curved back may bring the head further forward.

Leg support: To avoid that tight Hamstrings pull the pelvis posteriorly, aim for 90º knee flexion. The Platform Foot Support (9) is a good choice that also enables the user to vary the foot position. The Leg Supports with Fixed Angle (10) are available in two alternative knee angles. If Elevating Leg Supports (11) are chosen, always tilt and recline the chair before elevating the leg supports. This will reduce the risk for sliding forward due to tight Hamstrings.

Tilt and Recline Positions: Always make sure to assess both the active and resting positions. Secure the positions with Gas Piston Clips (12), Comfort Tilt Lock (13) and Back Angle Control (5). Anti-tippers: Always check the adjustment.

 

 

3D Back Support System
Three vertically placed soft cushions with plush cover, connected with sliding fabric and extra long tension adjustable back straps. It conforms perfectly to a curved back. Height adjustable between 45-60 cm (18"- 23½").

Dynamic Pelvic Support
Automatically relieves the tension in the reclined position and re-tightens in the active position. Adjust the height to the level of PSIS.

Tension Adjustable Back Straps
Make sure the user has good contact with the back support. Adjust the contour with the tension adjustable back straps.

Wedges
The back support can be further contoured with Cell Foam or Plush Wedges. They attach under the back cover with Velcro, included with the wedges.

5. Back Angle Control
By adjusting the length of the strap, the active back support setting can be controlled. The back will always stop at the preset angle. Note: The Back Angle Control will be available during 2019.

6. Contoured Seat Cushion
An anatomically contoured seat cushion stabilizes the position and helps to prevent forward sliding.

7. Positioning Belt
To provide a positioning support, the belt should be attach with not less than 70° angle to the seat frame.

8. Head Support
With adjustability in height angle and depth to meet the user´s head position. The head support can also be adjusted sideways.

9. Platform Foot Support
It provides a floor feeling that stimulates the user to vary the foot position. Foldable and height adjustable

10. Leg Support, Fixed Angle
A swing away model with flip up foot supports facilitate standing transfer. Available with 70° or 90° knee angle.

11. Leg Support, Elevating
The calf supports can be set in three different depth positions. Choosing the rearmost position and a generous heel strap adjustment, enable more knee flexion.

12. Gas Piston Clips
Each clip reduces the angling with approximately 2°. Can be used for both tilt and recline gas pistons. Easy to attach, easy to remove.

13. Comfort Tilt Lock
Stops the tilt position at a preset angle. Choose between: 0°, 4°, 8° or 12° seat tilt. The position can be changed by moving the locking device on the gas piston.
