Definitions

  • the present invention relates to a stowable vehicle seat .
  • Passenger cars and trucks are used for transporting passengers and cargo.
  • Passenger seats in vehicles limit the cargo carrying capacity of the vehicle.
  • Minivans and sport utility vehicles have various configurations of passenger seats that are adapted to be converted from a passenger seat to a folded cargo carrying position.
  • the seat back folds down over the lower seat . While this creates additional cargo carrying capacity, the folded seat back may be a foot to a foot and a half above the floor of the passenger/cargo compartment .
  • Another approach to the problem of maximizing cargo carrying capacity in a minivan or sport utility vehicle is to provide detachable seats that can be removed from the vehicle leaving a clear, unobstructed cargo floor of maximum height.
  • Conventional seats suffer from the disadvantage that they are heavy and unwieldy. Also, after the seats are removed from the vehicle, they must be stored outside the vehicle typi- cally in an already crowded garage.
  • Yet another approach is to provide seats that are mounted to the floor of a vehicle on rollers that are received in tracks secured to the floor of the vehicle.
  • the seats may be either rolled forwardly or rearwardly in the vehicle so that they are adjacent to one another when folded down.
  • one or more rows of seats may be removed. Depending on whether the seats are left in the vehicle in a folded down condition or removed, this approach suffers from the same disadvantages that were previously described.
  • the present invention is directed to solving the above problems .
  • a sliding side door for the vehicle permits access of passengers to a row of rear seats.
  • Contemporary minivans, as well as so-called sport utility vehicles furthermore may be provided with auxiliary seats rearward of the driver seat and the front passenger seat. These would be positioned on a platform or structural floor panel that accomplishes the secondary purpose of carrying cargo . In such instances the auxiliary seat must be folded forward to provide an extension of the cargo carrying floor area.
  • the stacked height of the auxiliary seat assembly in its folded state then would be equal to the sum of the height of the seat riser assembly, the height of the lower seat portion and the thickness of the seat back portion.
  • the overall stacked height thus is substantial in prior art designs. This is an inconvenience to passengers as they ingress and egress the vehicle through a side door opening.
  • the stacked height of the auxiliary seat assembly reduces the cargo carrying capacity of the vehicle when the vehicle is adapted for carrying cargo.
  • the present invention provides a vehicle seat for a vehicle, such as a minivan or sport utility vehicle, that may be folded down and rolled into a recess formed in the floor of the vehicle to provide a full height cargo area of maximum cargo carrying capacity.
  • a vehicle such as a minivan or sport utility vehicle
  • a seat for a vehicle that has a compartment that may be arranged in a passenger configuration or a cargo carrying configuration.
  • the floor of the compartment defines a recess in which the seat may be wholly or partially stowed.
  • Rear wheel housings extend into the compartment on opposite sides of the floor.
  • the seat includes a lower seat assembly and a seat back assembly that are pivotally connected. Rails defining channels are secured to the wheel housings on opposite sides of the compartment. Shiftable elements, or rollers, are connected to the rear portion on opposite sides of the lower seat assembly and are received in the channels defined by the rails.
  • Link arms are pivotally connected to the front portion of the lower seat and are also pivotally connected to the floor.
  • Locking pins associ- ated with the link arms are provided to selectively lock the shiftable elements to the rails.
  • the seat is converted from the passenger configuration to the cargo carrying configuration by pivoting the seat back onto the lower seat, disengaging the locking pins from the rails, and shifting the lower seat forward by moving the shiftable elements in the channels and pivoting the link arms forward and downward until the lower seat is received in whole or in part in the recess formed in the floor of the vehicle.
  • the rails may be provided with a series of holes spaced along a portion of their lengths.
  • the right and left locking pins may be selectively received in corresponding holes in the rails to permit adjustment of the seat fore and aft .
  • the locking pins may be secured to the link arms with a lever arm or other actuator connected to the locking pins for extending or retracting the locking pins.
  • a rear surface of the seat back is oriented in a sub- stantially horizontal plane when the seat is in the cargo carrying configuration.
  • the rear surface of the seat back may form a continuous surface with the floor of the compartment.
  • auxiliary seat assembly that overcomes the shortcomings of prior art designs such as those described in the preceding background discussion. This is accomplished in the improved design of the invention by providing a lower seat portion that consists of a tubular lightweight frame and that is connected through a parallelogram linkage riser to a seat base. Further, the seat back portion of the seat assembly comprises a lightweight tubular frame that is secured by a parallelogram linkage to a back panel and that is pivoted at its lower margin to the seat base so that it can be tilted forward over the lower seat portion.
  • the riser assembly for the lower seat portion when the seat back portion is folded forward, is shifted on its parallelogram linkage to a folded state.
  • the parallelogram linkage for the seat back portion allows the lightweight frame for the seat back portion to move toward the back panel .
  • the frame of the seat back portion engages the frame of the lower seat portion, thereby moving the latter as tilting motion of the seat back portion takes place.

  • the outer margin of the frame member 90 is provided with a channel 196 in which is received the margin of the foam rubber cushion 194, thereby holding the latter securely in place.
  • An elastomer fabric 198 is stretched across the lower seat portion and is anchored in the frame side members 90 and 92 in the manner illustrated schematically in Figures 9 and 9a.
  • the elastomer fabric is a woven fabric which yields under the weight of the passenger.
  • a material that has been successfully used for this purpose is manufactured by Acme Mills Company of Detroit, Michigan under the trade name "DYMATROL" .
  • the use of the elastomer fabric and the use of hollow frame members, which preferably are made of aluminum alloy, results in a very light weight seat assembly which reduces the weight of the vehicle. The reduced weight also makes it easier to assemble the seat assemblies and to carry the seat assemblies when they are removed from the vehicle.
  • Figure 7 shows a tandem arrangement for the foldable seat assembly of the invention.
  • the embodiment of Figure 7 functions in the same fashion as the embodiment of Figure 5 and the description of the mode of operation need not be repeated.
  • the reference numerals have been indicated in the embodiment of Figure 7 with prime notations in the case of the left-hand seat assembly and double prime notations in the case of the right-hand seat assembly. These numerals with prime notations or double prime notations correspond to the numerals designating similar structure in the embodiment of Figure 5.

Abstract

L'invention concerne un siège de véhicule que l'on peut plier et ranger dans un espace creux situé dans le plancher (16) d'un véhicule. Une partie arrière (28) du siège présente des éléments mobiles que l'on peut déplacer à l'intérieur de cannelures formées dans des glissières. Les éléments mobiles peuvent être des rouleaux se déplaçant dans des glissières à cannelures carrées. Une partie avant du siège est portée par des bras de liaison pivotant à mesure que le siège est escamoté dans l'espace creux. Des goujons (66, 68) de blocage situés sur les bras de liaison sont reçus dans une série de trous permettant le réglage vers l'avant et vers l'arrière de la position du siège. Un panneau de dossier de siège destiné au dossier du siège est porté par une liaison (130, 132) en parallélogramme. Le mouvement pivotant du dossier vers une position avant repliée s'accompagne d'un mouvement arrière de la partie de siège inférieure. Un dispositif d'élévation du siège et une liaison de dossier sont abaissés à mesure que le dossier est plié vers l'avant, réduisant ainsi la hauteur pliée totale du siège replié.
