Abstract

The device has a compressor (1) utilizing the energy of a vehicle and connected to a regulator. The compressor is connected by a pneumatic pipe (2) by a three way coupling with an option system. The regulator is managed by pneumatic controls (20, 21). The controls (20, 21) actuate the opening of solenoid valves (10, 12, 13, 14) for increasing or reducing the air pressure contained in a base and a backrest of a seat (7), respectively. A flexible pneumatic pipe (19) connected to the regulator supplies the air to the base and the backrest.

Celui-ci (1) est raccordé, par un tuyau pneumatique (2) (avec un raccord trois voies pour option (E) ) à un régulateur (3). Ce régulateur, étant relié par circuit (4) pour commandes+ et par circuit (5) pour contrôle pression, de manière à être géré par les commandes (20 et 21).  For a compressor (1) of the mechanical type, it will be coupled for driving, to a driving part of the vehicle. For an electric type compressor, it will be connected to an electrical part of the vehicle. The latter (1) is connected via a pneumatic hose (2) (with a three-way connection for option (E)) to a regulator (3). This regulator, being connected by circuit (4) for commands + and by circuit (5) for pressure control, so as to be managed by the controls (20 and 21).

Systèmes identiques pour option (E). La commande + et - (20) concerne l'assise du siège (6), la commande + et - (21) concerne le dossier du siège (7) (ces commandes électroniques peuvent être électropneumatiques ou pneumatiques). A tout moment l'occupant du siège: a) augmentera la dureté de l'assise de son siège (6), cela entrainera l'ouverture de 20 l'éléctrovanne (14) reliée par circuit (18) b) par pression sur la commande côté - (20), diminuera la dureté de l'assise, cela entrainera l'ouverture de l'électrovanne de purge (13) reliée par circuit (17) c) par pression sur la commande côté +(21), augmentera la dureté du dossier (7), cela entrainera l'ouverture de l'électrovanne (10) reliée par circuit (15) d) par pression sur la commande côté - (21), diminuera la dureté de son dossier, cela entrainera l'ouverture de l'électrovanne de purge (12) reliée par circuit (16). Systèmes identiques pour option (E) concernant a) b) c) d) ci-dessus.  Identical systems for option (E). The command + and - (20) relates to the seating of the seat (6), the command + and - (21) relates to the seat back (7) (these electronic controls can be electropneumatic or pneumatic). At any time, the occupant of the seat: a) will increase the hardness of the seat of his seat (6), this will cause the opening of the electrovalve (14) connected by circuit (18) b) by pressing on the control side - (20), will decrease the hardness of the seat, this will cause the opening of the purge solenoid valve (13) connected by circuit (17) c) by pressing the control side + (21), will increase the hardness of the backrest (7), this will cause the opening of the solenoid valve (10) connected by circuit (15) d) by pressing on the control side - (21), will decrease the hardness of its backrest, this will cause the opening the purge solenoid valve (12) connected by circuit (16). Identical systems for option (E) concerning (a) (b) (c) (d) above.

Un tuyau pneumatique souple (19) relié au régulateur alimente le circuit en air les électrovannes (10 et 14) la totalité du circuit est démontable grâce aux raccords unions (9) et raccords trois voies (11) entre autres. Des supports de soutien (8) pour parties pneumatiques sont prévus avec leurs fonctions traditionnelles d'avance/recul et d'inclinaison, etc, du dossier. La souplesse du circuit permet la dissimulation des électrovannes dans le véhicule dans un but d'esthétique et de commodité. Les commandes (20 et 21) sont installées à proximité de l'occupant du siège. Systèmes identiques pour option (E) concernant toutes les explications ci-dessus.  A flexible pneumatic hose (19) connected to the regulator supplies the solenoid valves (10 and 14) to the air circuit. The entire circuit can be dismantled thanks to the unions (9) and three-way connectors (11), among others. Support brackets (8) for pneumatic parts are provided with their traditional functions of forward / backward and tilt, etc., of the backrest. The flexibility of the circuit allows the concealment of the solenoid valves in the vehicle for the purpose of aesthetics and convenience. The controls (20 and 21) are installed near the occupant of the seat. Identical systems for option (E) for all explanations above.
