Ergonomic Wheelchair With Ventral Support

摘要

An ergonomic wheelchair with ventral support has an ergonomic shape where the person is placed in a position with support areas at the person's frontal area. The wheelchair is provided with a frame made of a reticular structure as a main support, mounted over four wheels, with the two rear wheels being much smaller and free to move in any direction. The structure has three main support surfaces: thoracic, femoral and tibial, each perfectly padded to achieve a proper distribution of pressure. The thoracic level can vary its length and inclination, the tibial support surface can modify its verticality, and the support surface of the thighs can be regulated for better anthropometric suitability. It is equipped with armrests for when the vehicle is self-propelled, and has two handles to allow another person to push it. A headrest with a visor avoids the tensions of having to hold the head up.

主权项

1. An ergonomic wheelchair with ventral support comprising a structure formed by a cross-linked frame mounted over four wheels, said wheelchair characterized because the front wheels are ergonomically customizable and it integrates with two structures that are linked together; wherein said frame provides support surfaces for a head, a thorax, an abdomen, thighs, legs and arms of a person; wherein the head support surface comprises an articulated arm that ends in a padded ring and is provided with a periscope that includes two separate mirrors placed obliquely; wherein the ventral thoracic support surface is located at an upper end of the frame that is linked by an articulated hinged quadrilateral reticular structure which supports a padded surface adaptable to the anthropometric differences that pivots on its rear end and which angle of inclination can be modified by the action of two gas struts that are operated through a lever; wherein the support surface for the thighs is placed next and comprises a slight tilt on the upper side; the thigh support surface has a padded surface and is attached directly to the frame, provided with removable lateral supports; wherein said support surface can be adjusted in length according to the movement of the tibial support surface below, and comprising a stable padded surface on its upper side located in a semi-horizontal position with a slight inclination towards the front linked to the frame by a quadratic structure.
