Tillett C1 Seat
The C1 is a lightweight competition seat from Tillett and is their first to feature head and neck protection. The C1 is based on the hugely popular B6 screamer seat and retains the compact dimensions and comfortable ergonomic shape but with improved safety. The head protection has been designed for optimum safety without hindering peripheral vision or shoulder movement. The B6 Screamer seat positions the driver lower in the car which benefits taller drivers and also helps lower the vehicles centre of gravity.
- Lightweight, from just 7.1kg
- Integrated head and neck protection to reduce the risk of injury in a crash
- Low seating position, ideal for lowering the centre of gravity
- Strong and rigid shell design increases driver feedback from the chassis
- Compact external dimensions allows fitment into smaller cockpits
- Suitable for most driver shapes / sizes. Standard size: Drivers up to 100kg with a 36" (91.4cm) waist/ XL Size: Drivers up to 130kg with a 40" (102cm) waist.
The Tillett C1 seat is manufactured in the UK and has been ergonomically designed to provide optimal comfort and body support without back or base padding. This allows for increased driver feedback from the chassis and also provides a lower seating position with increased legroom. The seat shell is super strong and rigid which is imperative to prevent the harness and FHR becoming loose in an impact. The C1 seat is fully compatible with harnesses and FHR devices and includes a 3 piece pad set made from impact absorbing foam which covers the head protection areas for extra protection. Base and back cushions sets are available to purchase separately if required.
The seat shell is made so that the outer edge can be either removed for narrow 41cm tubs or left on to create a continuous rolled edge around the whole perimeter of the seat (44cm wide). Also available in an XL size which is 3cm wider than the standard version. Like the standard seat it is available with the rolled edge (47cm wide) or with the edge removed (44cm wide).
