Definitions

  • a front seat for a motor-home which can seat two persons.
  • This is a bench seat which is provided with safety belts and a central column, but on which no seat elements with the requisite comfort can be arranged.
  • the column is herein placed behind the bench seat.
  • the present invention provides a securing member for securing one or two seat elements to the floor of a vehicle, wherein the member is provided with engaging locations for engagement of a safety belt.
  • the securing member is preferably an aluminium casting with a mass of about 20 kg.
  • the present invention further provides an assembly of a securing member and a rail which can be anchored to the floor of a vehicle. After testing of the anchoring of the rail in a particular vehicle having the securing member mounted thereon, seat elements of any manufacture can be fixed to the securing member since approval for these types of seat is obtained in all circumstances.
  • the rail further enables the arrangement of the seat elements in a bus to be changed at regular intervals in accordance with the wishes of the users.
  • a problem which occurs here is that the bus floor with the rail attached thereto can buckle under load whereby the seats can for instance be displaced during an accident, which is very dangerous and can result in injuries.
  • the assembly preferably further comprises a floor construction unit which can be arranged in a vehicle for securing of one or more seat elements to the floor of the vehicle, which floor construction unit comprises :
  • the rail element is provided with at least one securing location for securing a seat element to the floor con- struction unit and wherein the upper panel is provided with at least one opening corresponding with these secur ⁇ ing locations.
  • a floor construction unit which dissipates and absorbs the load forces which occur for instance during accidents, whereby buckling of the bus floor is substantially prevented.
  • the floor construc ⁇ tion unit provides a great bending stiffness.
  • the rails are preferably glued to the upper and/or lower panels.
  • a strong construction unit is obtained when in preference the rail is extruded integrally.
  • the rail has in cross section a base which supports on the lower panel, which base is wider than a cross section through the top part of the rail, which top part contacts the upper panel.
  • At least one support element preferably extends between the base and the top part of the rail.
  • the top part of the rail is preferably thickened locally close to the securing locations for the seat elements. This provides a good bending stiffness.
  • filler material is preferably arranged between the upper and lower panel.
  • This filler material must have a great shear strength and stiffness to prevent local buckling and damage of the panels and the rail element and must comply with fire safety requirements.
  • Suitable filler materials which can be considered are rigid foam (PVC, Rohacell) , elements with honeycomb structure (aluminium/Nomex) and balsa wood.
  • edges of the floor construction unit are preferably sealed with a seal in order to prevent degradation of the floor material due to the influence of moisture, heat or other factors.
  • the present invention further provides a vehicle such as a bus or the like for transporting persons, which vehicle comprises the above stated assembly.
  • the seats (with securing member) can quickly be removed from the vehicle and fitted therein again.
  • Wheelchairs, drive-on platforms, lifts, luggage compartments and the like can also be fitted to the floor via the openings therein.
  • the openings are keyhole-shaped.
  • fig. 1 shows a partly exploded view in perspective of a first preferred embodiment of an application of a securing member according to the present invention
  • fig. 2 shows a partly exploded view in perspective of a second preferred embodiment of a securing member for two vehicle seats according to the present invention.

  • Fig. 3b shows a view in perspective of securing members of fig. 3a with side supports on both sides;
  • Fig. 4 shows a view in perspective of an alternative of detail IV of fig. 3b.
  • Fig. 5 shows a view in perspective of detail V of fig. 4.
  • Fig. 6 is a partly cut-away perspective view of the floor construction unit
  • Fig. 7 is a side view of the rail of fig. 6, and
  • Fig. 8 is a side view of a second embodiment of the rail according to the present invention.
  • a securing support 1 (fig. 1) is a casting preferably manufactured from aluminium which is provided with recesses 2, 3 and 4 therein for further weight- saving.
  • two or more pins are preferably riveted or otherwise fixed to the underside thereof which can be placed at discrete locations into openings 5 of a rail 6 which is formed by a profile in the form of a reverse ⁇ .
  • Rail 6 is fixed to a floor 7 of the vehicle, preferably with screw bolts to a counter plate 8 which extends for further reinforcement under the floor plate 7 opposite rail 6.
  • Arranged on both sides of rail 6 are further floor plates 9, 9', for instance of wood, to which floor covering 10, 10' is attached, whereby rail 6 is flush-mounted in the floor.
  • the securing support can be arranged at different locations along the rail.
  • locking means can be arranged in the rail, for instance a cam which is rotatable with a ring spanner or the like and which engages on the securing support behind a forward protruding pin, likewise not visible in fig. 1, and thus locks the securing support in the adjusted position.
  • a lateral support construction 11 is fixed thereto, for instance using screw bolts, which comprises a triangular construction 12 to which are fixed girders 13 and 14.
  • a seat 15 of standard manufacture can be mounted on these girders 13, 14.
  • cross beams are usually situated under the seat part 16 of this seat element, which beams can easily be fastened to the girders 13 and 14.
  • the lateral construction including the girders is likewise formed as one casting.
  • the axis preferably deviates slightly from the vertical, particularly in the lower part of securing support 1, so that when only one seat element is fitted it is unlikely that on the other side a passing passenger will bump against the securing support with his feet .
  • a three-point safety belt 17 is fitted thereto in addition to a seat belt roll-up device 20 which is arranged close to the seat part of the seat for securing.
  • the third securing point 21 of the safety belt is situated close to the girder 13 on the triangular lateral support construction 12.
  • a lateral support construction 11' can likewise be mounted on which girders 13 ' respectively 14 ' are arranged so that on both sides seat elements provided with safety belts can be secured via the casting 1 to the floor of the vehicle.
  • a seat belt roll-up device 30 is fixed to the top end 19 of casting 1, while safety belts 31 respectively 32 extend downward from this seat belt roll-up device 30.
  • the casting is expected to have a weight of 22.5 kg with a weight- saving of 5 kg being gained by the recesses.
  • a second preferred embodiment of a securing member 30 (fig. 3a, 3b) is manufactured of composite material, i.e. an aluminium casting with plastic therearound. At the sides side supports 31 respectively
  • fig. 3a is arranged a single lateral support 31 of aluminium tube and plate parts which are welded or glued to each other, while in fig. 3b side frames 32, 32' are arranged on both sides.
  • Fig. 4 shows in more detail an alternative side frame 36, while fig. 5 shows the closing profile 35.
  • the securing member 30 or console is provided on the underside with so-called quick-closing pins with which the console can be fixed in rapid and simple manner to the floor of a bus.
  • the associated bus floor is preferably embodied as a sandwich panel .
  • the preferred embodiment of the column is constructed round an extruded trapezium-shaped aluminium profile. This profile is preferably provided with an internal ribbing in order to transfer to the floor panel the forces exerted by the side supports and the safety belts not shown in fig. 3-5. Wall thickness increases are applied locally in the extrusion profile to create sufficient material for securing locations provided with screw thread. In these threaded holes are fastened bolts with which the side supports, belts, quick-closing pins and the locking system are fixed.
  • the cavities in the extrusion profile are filled with foam and a foamed part core is arranged on the top of the extrusion profile. Filling of the extrusion profile with foam and foaming of the upper core can take place in one operation.
  • the assembled core of foam-filled aluminium extrusion profile and foamed part core is then finished in one treatment with a braiding process and carbon fibre is arranged therearound in lengthwise direction and at angles of +45° relative to the longitudinal axis.
  • the fibres prevent bending of the console, while the fibres at +/-45° absorb its load in the case of an eccentric load (embodiment with a single seat part or wherein one passenger is present on the embodiment with two seat elements) .
  • a small quantity of aramid fibre is preferably added during braiding as this has a greater breaking strain than carbon fibre and, in the case the console breaks, prevents a plane of fracture occurring which can cause danger to passengers.
  • thermocuring resin resin transfer moulding RTM
  • the side supports 31, 32 and 33 are frameworks of welded and glued aluminium profiles.
  • the load-bearing part of the side support is assembled from three main profiles 37, 38 and 39 (fig. 4) , the axes of which are mutually intersecting in the fastening point of the belt on the closing side.
  • This means that the profiles are oriented such that a rod construction is created in which the profiles are not under strain of bending but only under strain of tension and pressure.
  • On the console side end surfaces of the profiles are welded to an aluminium plate. -This plate is subsequently screwed against the console on the side of the belt fastening point and the profiles are glued in an aluminium casting 35. In the case of a crash the profiles under strain of pressure will press themselves fixedly into the casting.
  • a lighter con ⁇ structed part of the side supports comprises profiles 40 and 41 on the front side to which a seat element can be secured.
  • a floor construction unit 101 (fig. 4) has an upper panel 102, a lower panel 104 and a rail 106 arranged between the two panels 102, 104.
  • the floor construction unit is arranged on a bus floor 121.
  • Rail 106 can be made from an aluminium extrusion alloy such as for instance A150ST and preferably A151ST.
  • Rail 106 (see also fig. 7) is extruded with wider wing parts 108 in order to give rail 106 a broader base.
  • Vertical support elements 110 extend between the base 112 and the top part 114 of rail 106.
  • the top part 114 of rail 106 is provided with a plurality of keyhole- shaped apertures 116 for securing seats to floor construction unit 101.
  • the top part 114 is thickened locally in the vicinity of the securing apertures 116 (see also fig. 7) .
  • An alternative embodiment of the rail (fig. 8) is built up of three separate parts 120, 122, 124 which are glued to each other and also to a main profile 126.
  • This main profile 126 covers the parts 120-124 and extends on both sides in order to give base wing parts 128.
  • Seat element securing apertures 130 extend through both the main profile 126 and the upper part of the respective parts 120-124.
  • This embodiment of the rail is less expensive to manufacture than the extruded rail 106.
  • the rail has two rows of securing apertures 130 but it will be apparent that a single row or a plurality of rows are possible according to the present invention.
  • FIG. 6 are preferably made from a strong aluminium alloy, for instance A17075, since the tensions in the upper panel can rise during an accident for instance to about 400 MPa.
  • a filler material 132 is arranged between the upper and lower panels 102 respectively 104. Most preferably this filler material is a rigid foam of 300 kgm "3 , preferably PVC.
  • the keyhole-shaped securing apertures 116 in rail 106 and the corresponding openings 117 in upper panel 102 preferably have a diameter of 20 mm and a slot width of 10 mm in which steel closing pins of the securing member are connected to the seat elements (not shown) .
  • the screwable connection between securing support and floor is fixed by clamps.
  • the floor construction unit is assembled by gluing the rail, the floor material and the upper and lower panels.
  • a hot or cold curing epoxy adhesive system can be used for this purpose.
  • An anti-slip and anti-wear layer can further be arranged on upper panel 102 in order to provide a good grip for passengers.
  • the floor construction unit is assembled, it is then formed such that it has the correct outer contour depending on the bus floor. Finally, the whole unit is glued to the bus floor.
  • the mean tensile stresses occurring in this glue layer are low, with an order of magnitude of 1 to 2 MPa. At the position of the rail the stresses display high peaks due to the .local stiffness of the floor construction unit, wherein the maximum value depends inter alia on the geometry and stiffness of the bus floor. A strong and tough elastic glue system is thus recommended for gluing the unit to the bus floor.
  • Suitable glue systems are acrylate, modified two-component epoxy glues and modified silyl polymers (Simson ISR 70-03, 70-05, 70-08) .
  • mechanical connections such as bolts can be used between the bus floor and the unit according to the present invention.
  • the floor construction unit 101 (fig. 6) is manufactured for a bus floor of 3 m x 1.74 m 2 .
  • This floor construction unit 1 has the following dimensions:
  • This floor construction unit was subjected to a 20 g static collision test, wherein the following loads were measured for respectively a floor construction unit with two rows of seats and a floor construction unit with only one row of seats (see table 2, 3 respectively) .
  • the floor construction unit is tested by supporting it hingedly at the front and rear.
