  ABSTRACT :

 

When elderly people taking a trip, resting time can take up more than 50 percent of the journey, and 70 percent of resting time was in sitting posture. Based on literature review, average rest time during a trip was 8.6 minutes. Therefore, older people demand frequent and short resting time. For that reason, high sitting posture could be the answer, also for the universal design point of view, high sitting posture are more suitable for various age groups and users of different height.

This study focussed to review older people’s needs and problems, when taking a rest in public places. I have proposed high sitting posture seat incorporated with universal design, with one-size-fits-all design in mind. Firstly, high sitting posture seats materials and structures were analysed. Secondly, I conducted high sitting posture experiment, using experimental model for determining universal sitting high and scale for high sitting posture. Thirdly, expert review was carried out by employing PPP (Product Performance Program) to evaluate final design. Three main conclusions are as follows:

(1) Sitting position and height of seat: I chose 5 percentile of Gluteal furrow height as siting height for fairness and easy to use. Besides, the siting rail can be used for supporting passengers’ luggage and objects.
(2) Depth of seat: Because of high-seat position, the depth of seat was decreased. Consequently, I used unsymmetrical design for different sitting posture and people of different height.
(3) Backrest and armrests: Back rail of steel tube can be used as backrest.
