Lift assist systems and methods for adjustable seats

Abstract

Lift-assist systems for adjustable objects are provided, which could include at least one of an enclosed spring and a substantially flat, elongated torsion spring. Suitable substantially flat springs could be configured to twist and untwist up to between 45-135 degrees when the seat or other object is adjusted between stowed and use configurations. In some preferred aspects, the spring could be made from a tempered steel material.

AI Technical Summary

Benefits of technology

The system effectively supports heavy loads, reduces user effort in adjusting the seat, and maintains a sleek design by using a durable and cost-effective torsion spring that is protected from environmental factors, enhancing ADA compliance and safety.

Problems solved by technology

Unfortunately, many known systems are not suitable for use in bath tubs, showers or other wet environments, and are not ADA (American with Disabilities Act) compliant.

While there are some known seats that are ADA compliant, or suitable for use in tubs and showers, known seats often fail to provide any or sufficient lift-assist, or require external coil springs that could act as pinch points, detract from a sleek and clean looking seat system, and be sensitive to changing temperatures and water conditions.
