Seat

Abstract

A seat with a contoured pan comprises of two concavely shaped pads adapted to support the thighs of a user at an optimal angle to the horizontal plane. The seat further includes a linkage between the pads that allows for roll movement as a user sits on the seat. The combined features enable a user to be directed into a comfortable seating position that emulates the shape of the spine when standing.

Description

TECHNICAL FIELD[0001]The present invention relates to a seat; particularly a seat for use in an office chair, task chair, aircraft seat, bicycle, vehicle, wheelchair, pushchair, child's seat / car seat or bench. Specifically, the invention is a seat that actively directs the sitter into a correct sitting position as hypothesised by the inventor, i.e. a position that emulates the position that the sitter's spine and pelvis would achieve if they were standing.BACKGROUND ART[0002]Traditional chairs with near horizontal seat pans (both forward to back and side to side) force people to sit in a posture that is detrimental to proper functioning of their spines and associated tissues, which can lead to strain, injury and, in some cases, spinal degeneration. Specifically, horizontal seat pans force a sitting position with a curved back and reduced thoraco-abdominal space, so causing compression of the abdominal viscera, diaphragm and lungs which can result in hindered digestion and breathing....

AI Technical Summary

Benefits of technology

The present invention is a seat that can be used in bicycle and motorcycle seats. It has been designed to reproduce the natural position of the pelvis and spine when standing. The seat has two separate, concave shaped pads for each side of the user, which support the tissues and shapes around the ischial tuberosity. This structure enhances the body's natural cushioning features and reduces the need for excessive cushioning. The seat also has a leaf spring that helps in treating hypertonicity in the back muscles and allows for a controlled amount of roll in the seat pad. The use of standard bicycle saddles can be uncomfortable and cause health issues, but the present invention provides a comfortable and healthy alternative.

Problems solved by technology

Firstly, as most seats have horizontal or slightly downward sloping seat pans this does not allow the lumbar spine to achieve a stable position and so requires the overuse of insufficient spinal and paraspinal muscles to maintain an upright position.

These muscles are not meant to maintain an upright position for a sustained period.

Secondly, the human body is full of asymmetries, no place more so than in the legs, as they are the longest parts of the body.

When sitting on a normal, fixed, non-adaptive chair the pelvis is usually forced into a horizontal position, hence creating changes, stresses and discomfort on the spinal scoliosis.

Furthermore, it looks simple but has a high level of complexity and is a practical innovation.
