Definitions

  • This invention relates to vehicle seats, and more particularly to safety seat constructions such as are desirably provided for vehicles involved or likely to be involved in fire fighting, civil defence and other hazardous and life endangering operations; and in particular (but not confined to) operations involving the employment of operator emergency back pack equipment and where such as breathing apparatus is likely to be required to be used and is required to be quickly readily available to an operator in emergency conditions.
  • breathing apparatus employed for such as fire fighting and rescue operations comprises a back pack with a back support mounting an upright oxygen or air cylinder with attached user face mask, connecting tube(s) and control means, and with shoulder/upper body harness for fitment to a user.
  • Such apparatus with a full oxygen cylinder is weighty (eg typically in the region of 17-21 kilograms); and if not actually secured on the back of a fire fighter or other user, is accordingly required to be safely secured against free movement whilst in a vehicle travelling at haste to an emergency situation, for the avoidance of detachment and being thrown about to cause vehicle and equipment damage and/or injury to persons in the vehicle in the event of emergency braking or such as a crash - as may occur on occasions.
  • the apparatus when separately mounted within or on a vehicle in a securing cradle or the like, the apparatus is not readily available to or accessible by an operator for back fitment whilst the operator is seated in a vehicle during travel and with the necessary restriction of the vehicle seat safety belt or harness; and valuable, possibly life endangering, time is lost with the need for the operator to fit the breathing apparatus onto his/her back subsequent to the vehicle stopping and prior to being ready to undertake necessary action.
  • a. prevents the operator from being able to seat in a normal vehicle seat with safety and comfort
  • b. prevents or makes it very difficult for the operator to fit the legally required seat safety belt/harness
  • c. may cause injury to the operator in the event of a crash or emergency braking of the vehicle when moving at speed; with the additional applied force of the back pack and restraining safety belt/harness, d. may be likely, with the combined weight of the operator, to cause breaking or failure of the seat belt/harness and/or the normally employed vehicle seat in use; in particular the seat back, which may break or distort in the event of a crash or emergency braking of the vehicle, again with risk of injury to the seated operator and/or damage to the breathing apparatus.
  • An object of the invention in another aspect, is to provide a vehicle seat construction with a high strength back rest providing for recessed secure and quickly detachable fitment of a back pack breathing apparatus or other back pack emergency equipment of a similar nature, in a manner providing for comfort and safety of a seated operator and for harness fitment during vehicle travel whilst maintaining the seat safety belt/ harness safely fitted about the operator; thus saving valuable apparatus donning time and meeting or overcoming all of the aforementioned disadvantages and risks applicable to conventional and known specialised seat constructions for vehicles of the kind referred to and other special vehicles (including vehicles for air, ground and water travel.
  • the invention is similarly applicable to other apparatus and equipment employed in back pack form for emergency operations; and may for example be applicable to such as back pack fire extinguishers, acid and/or chemical or fuel spill control equipment using pressurised fluid (liquid/gas) containers such as cylinders or cannisters etc.

Abstract

Cet ensemble siège de sécurité (7) pour véhicule est conçu pour des interventions d'urgence et dangereuses, du genre lutte contre l'incendie et opérations de sauvetage. Cet ensemble siège (7) se présente sous une forme de siège unique ou multiple avec une structure de siège (11) destinée à chaque passager (9). Cette structure est construite à partir d'une tôlerie ouvrée et se présente comme une entité creuse pourvue d'une fixation d'assise (12) pour plancher de véhicule, définissant ou bien comportant une partie supérieure constituant un appui (17) et un dossier (7a), solidaire de la fixation d'assise (12), pour former des parties en colonne latérales, creuses, distinctes et réunies par une plaque arrière (14), s'étendant de bas en haut à partir de la fixation d'assise (12). Ce dossier définit un important évidement médian postérieur (6) pourvu des équipements de montage et de support (15) d'un réservoir de fluide sous pression (3) faisant partie intégrante d'un caisson dorsal de secours typique porté par l'occupant du siège(9) ou dont il doit s'équiper. De par leur construction et leur agencement, ce dossier (7a) et l'évidement (6) correspondant font que le support arrière (1) du caisson dorsal de secours vient s'aligner avec les parties latérales antérieures (ou le matériau de rembourrage les recouvrant (8d)) des colonnes latérales (8), le réservoir (3) étant installé dans l'équipement de support (15) à l'intérieur de l'évidement (6). Le dispositif comporte également des organes de rétention détachables (20, 22, 23) pouvant être actionnés par l'occupant et destinés à maintenir en place le réservoir du caisson dorsal de secours et son support (1). Les parties latérales antérieures, ou le matériau de rembourrage les recouvrant (8d), comportent des organes (8a, 8b) permettant de mettre en place et de maintenir temporairement des sangles de harnais (2), tout en permettant, lorsque l'occupant est assis sur le siège de sécurité (7), un bon ajustage dudit harnais, dont l'accès reste facile, sans risques d'enchevêtrement des sangles ou de restriction des mouvements de l'occupant (9).
