Definitions

  • the present invention relates to an integrated child seat frame configured for being integrated into a vehicle seat, the integrated child seat frame comprising a cushion support member, and a first and a second pivotable arm, each of which has a first end which is pivotally connected to the cushion support member, wherein the integrated child seat frame is adapted to assume both a first elevation and a second elevation, at which second elevation the cushion support member is elevated above its position at the first elevation.
  • Today, many vehicles are designed to comprise at least one child seat that is integrated into the vehicle seating system.
  • Such an integrated child seat is designed as an integral part of a vehicle seat for the purpose of seating a child in an elevated position on the vehicle seat in order to correctly position the vehicle seat belt over the child's body.
  • US 6,971 ,718 discloses an adjustable vehicle seat.
  • the adjustable seat comprises a squab element, two pair of links allowing the squab element to be moved upwardly from an initial position, in which the seat may be used by an adult, to an elevated position, in which the seat may be used by a child, and latches to maintain the seat in the elevated position.
  • an integrated child seat frame configured for being integrated into a vehicle seat, the integrated child seat frame comprising a cushion support member, and a first and a second pivotable arm, each of which has a first end which is pivotally connected to the cushion support member, wherein the integrated child seat frame is adapted to assume both a first elevation and a second elevation, at which second elevation the cushion support member is elevated above its position at the first elevation, the integrated child seat frame further comprises a pivotable central support arm arranged to retain the integrated child seat frame at the second elevation, wherein the first arm and a first end of the central support arm are adapted to form a releasable connection releasably connecting the central support arm to the first arm when the integrated child seat frame assumes the second elevation.
  • a vehicle seat comprising such an integrated child seat may assume an adult seating position, which corresponds to the first elevation and in which the vehicle seat is prepared for an adult, and a child seating position, which corresponds to the second elevation and in which the vehicle seat is prepared for a child.
  • the pivotable central support arm enables a robust and compact design of the integrated child seat frame and provides for a robust and reliable locking of the integrated child seat frame in the child seating position, i.e. at the second elevation.
  • the central support arm enables an integrated child seat frame that may be adjusted between an adult seating position and a child seating position in an easy manner.
  • an integrated child seat frame having relatively few parts may be provided.
  • the integrated child seat frame comprises a base structure to which a second end of each of the first and second arm and a second end of the central support arm are pivotally connected.

  • the second end of the central support arm is pivotally connected to the base structure adjacent to the second end of the second arm.
  • the central support arm and the second pivotable arm are pivotable around a common axis, which enables a robust design having very few parts since a common hinge pin may be used.
  • the first pivotable arm comprises at least one aperture configured to receive a connecting portion arranged at the first end of the central support arm.
  • said connecting portion comprises at least one tongue, the base of which is configured to engage an edge of said aperture, thereby forming said connection.
  • said tongue has a recess adapted to cooperate with a protrusion arranged at the edge of said aperture.
  • the integrated child seat frame further comprises a button device adapted for forcing the central support arm to release from its connection to the first pivotable arm in order to facilitate operation of the integrated child seat frame, i.e. to facilitate adjustment from the second elevation to the first elevation and/or adjustment from the first elevation to the second elevation.
  • the button device comprises a push button having a push surface at one end, which push surface is arranged to act on an abutment surface of the central support arm to push the central support arm away from its connection to the first arm.
  • the first pivotable arm is arranged to form a slide surface for the first end of the central support arm, wherein the first end of the central support arm is arranged to, during deployment of the integrated child seat frame from said first elevation to said second elevation, slide along said slide surface into the releasable connection.
  • the integrated child seat frame further comprises a spring element arranged to form a spring portion supporting deployment of the integrated child seat frame from said first elevation to said second elevation.
  • said spring element is configured to form a hinge pin portion connecting a respective second end of at least one of the first arm, the second arm and the central support arm to a base structure.
  • At least said first pivotable arm and said pivotable central support arm are formed from sheet metal.
  • This embodiment has the advantage that the frame may be very thin when it assumes the first elevation, i.e. in a folded state, which facilitates integration of the frame into a vehicle seat.
