Toilet with pelvic seat, foot support and deflector ramp

Abstract

Toilet with pelvic seat, foot support and deflector ramp. Odorless sanitary device with monolithic supporting body (7) that integrates: seat interface with adapted pelvic relief (1) with lateral ischial support zones (2) and longitudinal central relief channel (3); foot support platforms (4) at a lower level of 180-240 mm and horizontal distance D_h of 280-380 mm, whose geometry determines an angle α of the thigh with respect to the horizontal plane of 11º-27º, corresponding to a trunk-thigh angle of 63º-79º; and an internal deflector ramp (5) with variable inclination at 55º-65º and α2 30º-40º, which reduces impact energy and the generation of aerosols. The geometric relationship (1)-(4), derived from the inverse kinematics of the thigh-tibia chain for the P5-P95 percentiles (ISO / TR 7250-2:2024), configures the device for hygienic perineal access.The device jointly solves the ergonomic incongruity, structural instability, lack of evacuation control and perineal occlusion of the conventional toilet, without external accessories.
