Pelvic Positioning Part 1

Rifton Activity Chair Video 7

[00:00:09.15] Sam Durgin: Now we will show the pelvic positioning that we would like to offer with the activity chair. Every chair will come with a seatbelt. The seatbelt is mounted with this little white button. I can depress this with my pen and pull out the stamping, and that is the fastening point. The seatbelt itself has two padded sleeves that can slide so you have protection between the child’s hips and the strap, and there’s a buckle that’s in the center on the chair with two adjustment straps so you can keep it centered as you need to adjust it in and out.

[00:00:53.08] Sam Durgin: To keep the pelvis back on the seat is all-important. If the pelvis slides forward, then you lose the foundation of support for any upper body control you are trying to work with. So, we have provided some under-the-cushion supports. This is a lumbar support, and this we call an ischial shelf pad, or an anti-thrust pad. These can be mounted directly underneath the seat cushion. I’m going to tilt this forward so you can see what I’m doing. If I un-snap the front edge, and lift this up, I can adjust the seat depth to meet the needs of the child. Let’s say for this example, we have it almost all the way out. We take a measurement, and as a starting point, we suggest you take 2/3 of that measurement, draw a line on this pad and then cut it off with a pair of scissors. Then take this cushion and lay it on this seat right at the front edge. Re-snap your cushion, and this provides a little pocket of space that your ischial tuberosity can drop into and provide that bit of anti-thrust contour that we’re looking for. The lumbar support, is very similar. You can either remove the pad or stick it in from the side. Position it where you’d like a bit of extra lumbar support, and of course you can fine-tune that either by adjusting the backrest up and down or we’ll also provide sticky-backed Velcro. You can peel off the backing and affix it to the wood or the seat contour and then attach your cushion to it to position as you may need to.

[00:03:04.19] Sam Durgin: These are just starting points. The fact that we have cushions that have openings to the side should allow you to be able to put whatever detail contouring you may like to do, to meet the needs of your child.

Caption: Pelvic Harness:

[00:03:20.01] Sam Durgin: For some children, keeping the pelvis back on the seat is a really difficult challenge to solve. And for that, we have worked out a pelvic harness. I’ll install it instead of the seatbelt. So again, using my pen or my key, some pointy object, we have a child-proof release point that hopefully is not adult-proof. And we can attach our pelvic harness, ok? This has the same mounting hardware. I’m inserting this, depressing the white button and it snaps into place. Then we can position the child directly onto this cushion, onto this pad, and bring up these tails between the child’s legs, across the hip and back to itself with this buckle, which provides a harness to keep the pelvis of the child back on the seat. Now you do have two opportunities here of where to fasten this, and that will depend on the size of your child. I could reposition this whole arrangement back, to this farther back tab here, ok?
