Definitions

  • the invention relates to a hinge arrangement for a vehicle according to the preamble of claim 1.
  • the invention further relates to a vehicle comprising such a hinge arrangement.
  • the invention also relates to a method of mounting a windscreen in such a vehicle.
  • a vehicle such as a car, is normally provided with a bonnet, which covers an engine compartment.
  • the bonnet is connected to the vehicle by hinge arrangements, such that the bonnet can be opened in order to allow access to the engine compartment for maintenance and/or repair.
  • the bonnet is in American English often termed the hood.
  • the position of the rear end of the bonnet is in many vehicles determined by the space utilized when mounting a windscreen of the vehicle.
  • Document DE 10 2005 008 633 A1 discloses a hinge arrangement for a vehicle.
  • the hinge arrangement comprises a movable pivot axis at the connection to a body structure of the vehicle.
  • the hinge arrangement has two end positions: a closed position and a raised position, in which the bonnet is moved upwards and forwards.
  • a vehicle with a deployable bonnet If such a vehicle is involved in an accident, in which the front part of the vehicle hits a vulnerable road user, e.g. a pedestrian or bicyclist, it is not uncommon that the vulnerable road user is thrown onto the bonnet of the vehicle and that the head of the vulnerable road user impacts on the bonnet.
  • the bonnet In order to reduce the severity of these accidents the bonnet is adapted to be deployed when detecting a collision or an imminent collision. By raising at least the rear part of the bonnet to an "impact position", a so called deployed position or pop-up position, the distance between the bonnet and any hard engine parts is increased.
  • the bonnet may be lifted to the deployed position by means of an inflatable member such as an airbag, which may be activated by a pyrotechnical device.
  • the hinge arrangement of such a vehicle is arranged such that the bonnet can be displaced to the deployed position. Different variants of such hinge arrangement are known to the skilled person.
  • the object of the present invention is to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.
  • a hinge arrangement for a bonnet of a vehicle.
  • the hinge arrangement provides a hinged connection between the bonnet and the body structure of the vehicle.
  • the hinge arrangement comprises a first hinge member adapted to be attached, directly or indirectly, to the body structure of the vehicle, a second hinge member having a first end and a second end, and a third hinge member adapted to be attached, directly or indirectly, to the bonnet.
  • the first end of the second hinge member is pivotally connected to the first hinge member providing the hinged connection.
  • the second end of the second hinge member is movably connected to the third hinge member.
  • the hinge arrangement further comprises a positioning member, which is operable between the second and third hinge members to provide at least a first and a second position of the hinge arrangement.
  • the hinge arrangement is movable between the first and the second positions, wherein a portion of the third hinge member being furthest away from the connection to the second hinge member has a larger distance to the second hinge member in the second position than in the first position of the hinge arrangement.
  • the positioning member is adapted to restrict relative movement between the second and third hinge members, such that in the second position of the hinge arrangement, the positioning member is adapted to prevent the second and third hinge members from moving closer to each other.
  • the first position of the hinge arrangement preferably corresponds to a generally closed bonnet, while the second position of the hinge arrangement preferably corresponds to bonnet being in a mounting position or an alternative mounting position, which positions are further described below.
  • the mounting position and the alternative mounting position are suitable positions of the bonnet when mounting a windscreen in the vehicle. These positions are also suitable for removing the windscreen or exchanging the windscreen.
  • the first and the second position of the hinge arrangement define different positions of the hinge members comprised in the hinge arrangement relative to each other.
  • the second position should not be mixed up with the above-mentioned deployed position or pop-up position, which is used in a vehicle with a deployable bonnet.
  • the invention as disclosed herein is applicable for vehicles with standard bonnets, as well as for vehicles with deployable bonnets. If the vehicle is of the kind having a deployable bonnet, it is to be noted that the second position of the hinge arrangement as disclosed herein is not the same thing as the position of the hinge arrangement which is assumed in the above-mentioned deployed position or pop-up position of the bonnet.
  • a hinge arrangement allowing a small gap between the rear end of the bonnet and the windscreen, yet allowing easy mounting of the windscreen is provided.
  • the positioning member is operable between the second and third hinge members to provide at least the first and the second position of the hinge arrangement.
  • the positioning member "being operable" means that the positioning member acts at least between the second and third hinge members.
  • the positioning member may be attached to either of the second and third hinge members or it may be a separate unit intended to be placed between the second and third hinge members. One or both of the second and third hinge members may abut on the positioning member.
  • the positioning member may be arranged to only act between the second and third hinge members, thus not influencing the relative movement between the second hinge member and the first hinge member.
  • the positioning member is typically located in the space between the second and third hinge members or adjacent thereto, at least when the hinge arrangement is in the second position of the hinge arrangement, but preferably also when the hinge arrangement is in the first position and during transitions between the first and second positions.
  • the positioning member is arranged to prevent downward movement of the bonnet in the second position of the hinge arrangement.
  • the positioning member may in the second position provide a predetermined minimum distance between the end of the third hinge member and the second hinge member.
  • the third hinge member has a larger distance to the second hinge member in the second position of the hinge arrangement than a distance from the third hinge member to the second hinge member in the first position of the hinge arrangement.
  • the distance is defined as the closest distance between the portion of the third hinge member being furthest away from the connection to the second hinge member and the second hinge member.
  • the third hinge member may have an elongate shape and comprise a first end and a second end, which is opposite to the first end.
  • the first end of the third hinge member may be movably connected to the second end of the second hinge member.
  • the second end of the third hinge member is the portion being furthest away from the connection.
  • the second end has a larger distance to the second hinge member in the second position than in the first position of the hinge arrangement. It is possible to connect the third hinge member to the second hinge member anywhere along the length of the third hinge member.
  • the positioning member may further be adapted to in the first position of the hinge arrangement prevent the second and third hinge members from moving away from each other. This helps to avoid, or at least minimize, the risk of a rattling noise arising from the bonnet, e.g. when driving over uneven ground.
  • the positioning member may be attachable, directly or indirectly, to the second hinge member and/or to the third hinge member. If the positioning member is attached, the risk of dropping it or losing it is avoided, or at least minimized. However, it is also feasible that the positioning member is a separate, loose component, i.e. neither attached to the second hinge member, nor to the third hinge member.
  • the positioning member may be adapted to in the second position of the hinge arrangement hold the second and third hinge members in a fixed position relative to each other. This gives a stable position of the bonnet when mounting the windscreen.
  • the positioning member may be adapted to in the first position of the hinge arrangement hold the second and third hinge members in a fixed position relative to each other. This helps to avoid, or at least minimize, the risk of a rattling noise arising from the bonnet, e.g. when driving over uneven ground. Further, the risk that the third hinge member is displaced relative to the second hinge member during e.g. adjustment of the bonnet or if a load is applied in the transverse direction T, e.g. due to a side collision, is reduced or avoided.
  • the hinge arrangement may be configured such that a displacement between the first and second positions of the hinge arrangement involves a rotational and/or a translational movement of the third hinge member in relation to the second hinge member.
  • the movement may occur around a second pivot axis, e.g. being located at the second end of the second hinge member and/or in slot/s provided in either, or both of, the second and third hinge members.
  • the shape/s of the slot/s may then determine the relative movement between the second and third hinge members.
  • the second and third hinge members may in the first position of the hinge arrangement be substantially parallel to each other. Thereby the hinge arrangement may use the available space below the bonnet in an efficient way.
  • the second and third hinge members may in the second position of the hinge arrangement assume an angle ⁇ 2 in relation to each other, the angle ⁇ 2 being between 1 and 40 degrees, preferably between 5 and 25 degrees.
  • the angle ⁇ 2 may e.g. be between 10 and 20 degrees. These angle ranges have been found to be suitable to provide space for mounting the windscreen.
  • the angle ⁇ 2 may be determined as the angle between the longitudinal axes of the third hinge member and the second hinge member, e.g. at the above-mentioned second pivot axis.
  • the angle ⁇ may further be an angle ⁇ between the longitudinal axes of the second hinge member and the first hinge member.
  • the angle ⁇ 2 of the second position of the hinge arrangement may be between 1 and 40 degrees, preferably between 5 and 25 degrees, larger than the angle ⁇ 1 of the first position.
  • the angle ⁇ 2 may e.g. be between 10 and 20 degrees larger than the angle ⁇ 1 .
  • the angle ⁇ may be determined at a first pivot axis between the second hinge member and the first hinge member, which first pivot axis provides the above-mentioned hinged connection.
  • Suitable values for the angle ⁇ between the longitudinal axes of the second hinge member and the third hinge member and for the angle ⁇ between the longitudinal axes of the second hinge member and the first hinge member depend on the configuration of the hinge arrangement.
  • the second and third hinge members may in the first position of the hinge arrangement be biased in a direction away from each other but retained in the first position by means of the positioning member. This helps to avoid, or at least minimize, the risk of a rattling noise arising from the bonnet, e.g. when driving over uneven ground.
  • the biasing may be provided by a spring member or a member of resilient material located between the second and third hinge members biasing the second and third hinge members away from each other at least in the first position of the hinge arrangement.
  • the positioning member may comprise a catch attached to one of the second and third hinge members and adapted to hold the other of the second and third hinge members in the first and/or second position of the hinge arrangement.
  • the catch may be located between the second and third hinge members, e.g. adjacent to the end of the third hinge member, or the catch may be located at the end of the third hinge member.
  • the catch may be pivotally attached to the one of the second and third hinge members, such that it can be rotated between two positions corresponding to the first and the second position of the hinge arrangement, e.g. rotated out of the way or rotated between two different abutment positions.
  • the positioning member may comprise a fastening member, such as a screw, bolt or biased pin.
  • the fastening member is arranged to in the first position of the hinge arrangement hold the second and third hinge members together in a predefined relative position, and in the second position of the hinge arrangement hold the second and third hinge members together in a different relative position.
  • the fastening member may be attached to either of the second hinge member or the third hinge member or it may be a separate unit.
  • the positioning member may comprise an abutment member, such as a screw, bolt or biased pin, the abutment member being arranged such that in the first position of the hinge arrangement the abutment member holds the second and third hinge members together and in the second position of the hinge arrangement, the third hinge member abuts on the second hinge member via the abutment member.
  • an abutment member such as a screw, bolt or biased pin
  • One of the second and third hinge members may comprise a positioning portion, which has a shape element, such as a slot or a notch, providing at least one of the first and second positions.
  • the positioning member is attached to the other of the second and third hinge members, such that the positioning member may be displaced in and out of the shape element.
  • the positioning member may then be biased to stay in the shape element, e.g. by a spring member or a magnet.
  • a vehicle comprising a bonnet, a body structure and at least one hinge arrangement according to this disclosure.
