  • Expandable active header with side support is
  • This initially inactive header is like a common and current header subject to two posts to regulate the height with regarding the backrest of the armchair. It consists of four pieces, two central shaped hollow helmets to house the expansion mechanism, one fixed attached to the posts and the other mobile, which is the one that makes the approach to the head, both central helmets are joined by a spring spiral and encapsulated in two metal tubes, one tube attached to the fixed hull and the other tube of smaller diameter attached to the mobile hull this tube enters into the other and into both the spiral spring. It will be kept compressed and encapsulated as a closed telescope and locked by a latch attached to a solenoid.

Abstract

L'invention concerne un système électro-mécanique qui, à l'état passif, ressemble à n'importe quel appuie-tête, fixé à deux montants (13 et 14) permettant de régler la hauteur de l'appuie-tête par rapport au dossier du siège. Ce système est divisé en quatre parties. Il comprend deux parties centrales en forme de boîtiers creux pouvant loger le système d'extension, dont une partie fixe (4) unie aux montants (13 et 14) et une autre partie mobile centrale (5), reliées par un ressort (3) contenu dans deux tubes en métal (6 et 7) télescopiques fermés et entravés par un mécanisme de sécurité (2) connecté à un solénoïde (1). Les deux autres parties sont latérales (8 et 9) et comportent un axe (10) à leur extrémité supérieure avec une barre, traversant la partie mobile centrale (5) dans sa partie supérieure, dans laquelle on introduit un ressort hélicoïdal (11) entravé et tourné dans le sens positif, chaque barre comportant une broche (12) qui sert de sécurité pour le ressort (11) et qui se fixe au crochet (16), lesdites broches constituant le sommet des pièces latérales (8 et 9) qui limitent la rotation à 90° dans le sens négatif. L'appuie-tête est activé lorsque les capteurs de choc postérieur et/ou latéral envoient un signal électrique au solénoïde (1), ce qui libère la sécurité (2) et déploie le ressort (3), libérant ainsi les broches (12) et par conséquent les pièces latérales (8 et 9). Le câblage électrique part du solénoïde (1), vers les capteurs, par le canal interne (15) traversant les montants (13 et 14), et se termine par une fiche de connexion.
