LOW BACK CAR SEAT WITHOUT HEADREST, FOR PERFORMANCE AND TRACK DAY CARS.
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.
