Designed for DxRacer office chairs, to hold the strap of the head rest included with the chair through the holes instead of wrapping it around, which makes it much more stable.
To my knowledge, this piece was never produced by the company as I never seen any reference to it except for a small 2 cm x 2cm design in the chair instruction manual. I was curious to see if it would work, so I designed it as close as possible to that small design, and it works great.
The strap can be attached in many different ways, depending on the chair model, but will obviously only work with models that includes the bucket seat hole(s) originally designed for the car's safety belts.
In addition, the strong & flexible materials are ideal for this type of piece, making it very sturdy, but still flexible enough to bend it a bit to help insert or remove the strap.
