THE W1i - CAR SEAT
The low back W1i Tillett car seat is internally the same shape as our standard B6 but without the headrest. This light and compact seat can accommodate a driver up to approximately 100 kg with a 36 inch jeans waist size. There is a choice of a carbon or black GRP front finish and two specifications of edge cut in the leg support area.
The W1i-40 version has a trimmed edge to allow fitment between the gearbox tunnel and the door sill of narrow vehicles, such as a Lotus 7 replica. We call this the “edges off” model.
The W1i-44 has the rolled edge left on “edges on” to give a more aesthetically pleasing look to the edge of the seat and is advised if you have the room.
The W1i is also available as a single skin shell, or with a floor mountable backframe. The backframe consists of a second composite moulding bonded to the front skin, making the W1i a fully self-supporting rigid structure. Its four M8 embedded fittings can be in the bottom or the side of the backframe.
“Bottom mounts” allow it to mount directly to the floor using a spacer, or on top of the Tillett seat adjustment runners using the TK5 fitting kit.
With the side mount option, it is possible to use the same 2° race brackets as used by the FIA B6 and B7 seats. The weight of a W1i with the backframe is 3.5 kg and 1.9 kg without.
Low back W models are most suitable when a headrest is not practical, maybe for an application where there is already a headrest support in existence. The W1i shape is often suited to Formula Student university projects.
