Bifold torque hinge for thinner fold-out tables in transportation interiors

Southco has expanded its line of bifold constant torque hinges with the AH-2E-12, designed for thinner fold-out tables used in passenger transit interior applications. The AH-2E-12 uses friction to increase control of 180 degree fold-out tables, preventing the flaps from falling open during operation and improving the end user experience.

The bifold constant torque hinge product line has been expanded to allow for installation in panels as thin as 12mm (1/2 inch). The new AH-2E hinges complement the existing bifold hinges which were designed for 20mm (3/4 inch) panels. Many engineers are looking for solutions for thinner panels to reduce the size and weight of their designs.

Southco says the AH-2E bifold constant torque hinges provide consistent, smooth operation, allowing passengers to safely position fold-out tables on moving vehicles such as trains, airplanes, and motor coaches. Integrated constant torque allows the table to be held in position at any angle, preventing it from falling open while the vehicle is in motion. With improved aesthetics and enhanced reliability, the AH-2E is an upgrade from traditional free-swinging hinges and dampening devices.

With its flush mount design, the AH-2E bifold constant torque hinge occupies minimal application space and allows a table to be deployed to a secure horizontal position and folded and stowed flat. Constructed of robust materials, the AH-2E delivers reliable, maintenance-free performance and delivers enhanced safety, with its controlled motion preventing trapped fingers and flush design eliminating pinch points along the joint.

Global product manager Stewart Beck says: “The AH-2E bifold constant torque hinge achieves a new level of safety and performance for fold-out tables in passenger transit applications in the rail, bus and coach and aerospace industries. With its integrated constant torque technology, the AH-2E provides an upgrade from existing free-operating solutions by enabling controlled motion that keeps the table from falling open onto the passenger’s lap.”
