LEXUS KINETIC SEAT CONCEPT WORLD PREMIERE AT THE 2016 PARIS MOTOR SHOW
- Revolutionary fibre net construction re-evaluates the principles of car seat occupancy.
- Rotational movement of seat cushion and back rest simulates the fundamental spinal movements of human mobility to help enhance head stabilization.
- Spider web-pattern flexible net closely fits body shape, dispersing load for prolonged seat comfort and optimal body support.
- Threads at the back rest of the spider web-pattern construction are made from environmentally-friendly, synthetic spider silk materials.
MOVABLE SEAT CUSHION AND BACK REST
In humans, the spine acts to stabilize the head. It allows the pelvis and chest to rotate in opposite directions, stabilizing movement of the head even while walking or jogging.
In order to recreate this movement in car seats, the seat cushion and back rest were designed to move kinetically with occupant weight and external forces. Thus, simply sitting in the seat helps stabilize head movement caused by vehicle motion, keeping the field of vision steady. This reduces the burden on occupants, improving ease of driving and comfort.
SPIDER WEB-PATTERN NET SEATS
The seat frame 'upholstery' comprises a spider web-pattern net with threads that spread out radially from the center of the back rest. The net is sufficiently flexible to closely fit body shape, dispersing the load to make it possible to sit comfortably for prolonged periods.
The center of the back rest is at shoulder blade height, which induces rotational movement of the chest around the seat's pivotal axis. This helps to stabilize the head and ensure a high level of support. The seat has also been made slimmer, making the overall car lighter in weight.
SYNTHETIC SPIDER SILK
The threads at the back rest of the spider web-pattern construction are made from environmentally-friendly, synthetic spider silk materials* instead of petroleum-derived materials. The main component of this material is protein, which is created through microbial fermentation, then spun and processed into a new material offering superior shock absorbance (Toughness) properties.
*QMONOSTM material developed by Spiber Inc.
The Kinetic Seat Concept will be shown on a stand-alone display for the first time at the 2016 Paris Motor Show.
