Definitions

  • Seats in particular for public transport vehicles such as busses, vans, subways, trains, planes, ferries etc., need to be positioned side by side and one behind the other on the floor of the passenger cells.
  • the seats are located on support elements, usually in the shape of legs or similar, with which the seats can be mounted on the floor of the vehicle chassis, preferably in rails being embedded in the floor.
  • Prior art support elements or legs for such kind of seats are made of metal providing a substantial strength.
  • Vehicles for public transportation are mainly used for short distances and frequently used by different types of passengers, thus the weight load acting on those seats and thus on their legs changes constantly.
  • public transport requires certain safety standards in an event of accident so as to keep such seats intact and firmly mounted inside the vehicle, in
  • TR 2016/13398 discloses a locking mechanism in connection with seat legs to install seats on installation railings in
  • the locking mechanism includes a winding arm that fixes the seat legs on rails in the floor, having an eccentric structure, in which an
  • eccentric pin is connected to the winding arm and a rondel prevents the winding arm to go into the rail space, while installation holes are provided to install locking legs.
  • Quick changing legs for seats are e.g. known from TR 2016/08447 which legs can move inside the receiving rails when more space is required and can be folded to provide space for e.g.

  • Another advantage of this new inventive concept is that such support elements casted as an aluminium monobloc construction can be manufactured faster than metal types, which reduces the production costs substantially. Further, since no welding process is needed in particular during installation in the vehicle, such novel support elements can be installed more easily and quicker.

  • the central structure which is preferably plate-like, may comprise a series of recesses or openings .
  • such series or arrangement of recesses may differ depending on the operation purpose of the seat, i.e. the range of total weight and/or maximum load to be carried by it.
  • distribution and/or the orientation of such recesses within the central structure may be configured and designed to allow for weight reduction with respect to the support element to the maximum possible extent without influencing the strength, which in fact depends on said maximum load to be carried by the support element, namely with of the seat and possible weight range of passengers.

  • the seat connecting element may comprise means for correctly aligning a seat during installation. By that, fixation holes for bolts do automatically match and the seat can be placed on top of the support element in one determined position only, at least with respect to one direction, which further eases the installation process.

  • the monobloc support element with its frame structure, central structure and recesses in its entirety is configured and designed to not comprise any notches or edges, which would otherwise result in force surges and progressive force collection when the seat and thus the support element is under load. Since according to the invention such geometric structures do not appear, notch effects, which could lead to material failure and fatigue, are avoided completely.
