摘要

The armchair has a chassis (1) supporting a base (2) and a backrest (3), and side wheels (5) mounted on the chassis. Dynamometer measuring sensors comprise six-components (71, 72) arranged at the base and the backrest to measure forces and moments exerted by a user on the base and the backrest. The chassis comprises tubular elements constituting upper and lower rails (11, 12), front and rear posts (13, 14) and a rear traversing tube (17) assembled between each other by a connection unit (8) adjusted at a position, and the connection unit is made of a composite plastic material. The tubular elements constituting the chassis are made of carbon fiber.
