Recliner backrests
A locking unit controls backrest positioning through the seat linkage.
Match the locking gas spring and release system inside an adjustable seat. Browse published base references by stroke and length, then specify force, attachments and the movement you need to control.

A release control allows adjustment; closing the valve holds the selected position. Elastic or rigid locking behaviour must suit the seating mechanism.

A locking unit controls backrest positioning through the seat linkage.
Headrest, armrest and backrest mechanisms have different travel and connection needs.
Confirm the release pin, head, cable travel and lever operation as a complete combination.
Use the original marking or a drawing wherever possible. Measurements may be supplied in millimeters or inches.
Existing part code, elastic or rigid holding action, and adjustment position.
Extended/compressed dimensions and stroke on the relevant drawing.
Marked force or selected base-reference force; thread, clevis or eyelet details.
Release-head type, cable/lever arrangement and required quantities.
These are configurable base references, not verified replacements for a named recliner brand or model. Final mounting centres depend on the selected end fittings and release head.
Choose a reference and include your quantity. Each record keeps its original dimensional scope and a link to the source.
Published application references help identify your request. They are not Horizon stock codes. Confirm the exact assembly, fittings and quantity in your quotation. Unpublished specifications are left open for matching.
