Lockable gas springs with special functions

With the Varilock lockable gas springs, the SUSPA® expertise is in particular distinguished by the finely mechanical valve design, which allows for a variety of special functions to be realized. The user thus not only receives a gas spring, but rather an intelligent system that adds indispensable added value to the application.

  • EasySwitch ES: Locking that can be switched on and off

    The "EasySwitch" module gives the user the opportunity to control the valve "digitally," namely alternating from the closed to the permanently opened position and back.

    The change between the two states is controlled by actuating the control element. With a chair, the EasySwitch keeps the valve open (oscillating feature) or closed (locked backrest) after actuation.

  • OverRide OR: Convenient extension without actuation

    The "OverRide" module makes it possible to release the locking in the extension direction without actuating the release. For table applications, the height is adjusted by applying a slight pulling force on the tabletop. Once reaching the desired position, the locking is rigid in the pressing direction.

    OverRide causes an extremely convenient operation that was originally designed for use in hospital beds and side tables. OverRide in particular allows for the single-handed actuation of the application.

  • TimeReset TR: Automatic reset

    The "TimeReset" module automatically detects whether the application is loaded with a user weight or not. Under load, the lockable gas spring works conventionally and allows for variable locking. When the application is not loaded, the lockable gas spring returns to its starting position (vertical backrest) within a defined time period.  

    TimeReset is particularly suitable for passenger seats, cinema and theater seating or conference chairs.

  • ComfortReleaseLow CL: Extremely easy operation of gas springs

    Lockable gas spring with ComfortReleaseLow function

    Using the "ComfortReleaseLow" module can adjust the lockable gas springs to the requirements of any release system in order to achieve maximum operating comfort. Conventional valve designs (standard release) cannot be conveniently triggered in the event of high extension forces. SUSPA® ensures a convenient release through the lowest possible manual force on the actuating element (knob, lever). We are happy to advise you in the optimization of your application.

  • Lightweight lockable gas spring

    Lockable gas springs for aviation are ideal for the comfortable and safe adjustment of the sitting and lying position of passenger and pilot seats.

    Special features

    • Optimized weight due to the aluminum piston rod (60% weight savings compared to a conventional piston rod made of steel with the same performance)
    • High strength tube with less wall thickness (25% compared to conventional tubes)
    • Low release force
    • High spring stiffness


    Application Examples

    • Backrest adjustment in passenger and pilot seats
    • Leg rest for business and first class seats
