DAESSY Mounting System
Mounting on a Tilting Seat System
When mounting a communication device or laptop on a wheelchair with a tilting seat system special considerations must be made. This information describes the considerations to make for each of the DAESSY standard mount assemblies. On a wheelchair with a tilting seat system the Frame Clamp Assembly is attached to the seat rail or seat frame; this will allow the mount to move with the user when tilted and allow the user to continue accessing the device.
Rigid Mount (DRM1) & Folding Mount (DFM2)
The standard Rigid Mount and Folding Mount can be used with a tilting system up to a moderate angle of tilt, but when the mount is to be tilted past 15 degrees from vertical the increased load on the index pin will lead to premature wear and elongation of the hole in the Index Clamp.
When mounting on a tilting system the Removable Outer Piece versions of the Rigid Mount and Folding Mount is the preferred version.
When the tilt exceeds 15 degrees the Rigid Mount is the best choice as this mount may be installed with the vertical tube tilted forward when the seat system is upright which reduces the overall rearward tilt the mount undergoes. This forward tilting installation cannot be used for the Folding Mount; the Folding Mount must be installed truly vertical due to the folding motion.
Rigid Mount ROP Version (DRM1ROP) & Folding Mount ROP Version(DFM2ROP)
A Removable Outer Piece and Receiver replace the standard Frame Clamp Outer Piece and Index Clamp to give the ability to lock this mount in the frame clamp; particularly for use on a wheelchair with tilting seat system.

Locking Swing Away Mount (DLSA7)
The Locking Swing Away Mount is not appropriate for mounting on a tilting system. It must be installed truly vertical and remain vertical at all times during use.
Rear Folding Mount (DRFM6)
The Rear Folding Mount is not appropriate for mounting on a tilting system. Refer to the Lockable Rear Folding Mount.
Lockable Rear Folding Mount (DLRFM8)
The Lockable Rear Folding Mount is the preferred rear folding mount for use on wheelchairs with a tilting seat system. With the mount locked in front of the user the stability of the mount is not affected when the seat system is tilted.
When the mount is folded to the rear it is possible that there will be interference with the mount when the seat system is tilted. This must be considered and clearances checked when fitting or evaluating this mount assembly for a wheelchair with tilting seat system.
The Locking Rear Folding Adapter should ideally be located halfway between the front and rear folded positions for the mount so the folding motion of 90 degrees give equal inclinations of 45 degrees front and rear. The Lockable Rear Folding Mount does have the capability of a folding motion greater than 90 degrees and it is possible to split the folding motion unequally between the front and rear positions, however, when the mount is installed forward of the halfway location the side tube length may not be sufficient for correct folding. When the mount is installed behind the halfway location the side tube length required might be so long that in the folded position it will likely protrude beyond the rear of the wheelchair significantly.
