CA 2246021

A chair seat tilt lock comprises a slider riding along a track on the seat and an abutment extending from chair seat post. The slider is spring biased into registration with the abutment to block the chair against tilting and may also be moved away from the abutment so that the chair is then free to tilt. The slider is mover by a lever arm connected to the slider by a co-axial cable with an enlargement at the end of the inner cable which allows the cable to be releasably press fit into a skeleton key-shaped passageway through the slider.

Cette invention concerne un mécanisme de verrouillage de chaise inclinable qui comprend un coulisseau mobile le long d'une tringle et une butée en saillie sur la tige porte-siège. Le coulisseau est poussé par un ressort contre la butée pour empêcher la chaise de s'incliner, mais il peut être éloigné de la butée pour permettre l'inclinaison de la chaise. Le coulisseau est manoeuvré au moyen d'un levier raccordé à un câble coaxial dont le brin intérieur porte un renflement à son extrémité libre destiné à permettre l'assemblage amovible à force du câble dans un logement en forme de crochet de serrurier du coulisseau.
