Definitions

  • the invention relates to a vehicle seat with the features of the preamble of claim 1.
  • a vehicle seat of this type with a restraint device which, in the event of a crash, pyrotechnically triggered pulls a belt buckle downwards and, by means of an expansion joint, sets up a pivotable seat wedge provided in the seat cushion, which acts as an anti-submarine ramp.
  • the invention is based on the object of improving a vehicle seat of the type mentioned. This object is achieved according to the invention by a vehicle seat with the features of claim 1. Advantageous refinements are the subject of the dependent claims.
  • the anti-submarine ramp is movable in a recess in the seat cushion, ie within the same, prevents cushion pressures in the seat cushion which counteract movement of the anti-submarine ramp.
  • the maximum comfort is normally achieved.
  • the active anti-submarine ramp preferably stiffens the normally resilient seat cushion. Comfort is only reduced in the event of a crash.
  • the movement of the anti-submarine ramp requires only a small amount of energy since neither the occupant is must still be pressed foam, but only the existing recess must be filled or supported.
  • the shape of the recess and the mobility of the anti-submarine ramp are coordinated with one another, ie the shape of the recess results primarily from the space which the anti-submarine ramp traverses during its movement from a rest position into an active position, preferably while straightening and / or smoothing the Room surrounding upholstery.
  • Non-load-bearing and non-supportive, that is to say in particular protruding convex upholstery parts are avoided.
  • the active anti-submarine ramp has one
  • Bracket which is pivotable within the recess, in particular pivotable from a flat position (rest position) to an erected position (active position), the latter being defined, for example, by a stop.
  • the term “stirrup” is intended to be interpreted broadly in the present case, so that other structural components, for example a sheet metal plate, can also be included here.
  • the term “flat” is intended to describe an essentially horizontal arrangement, for example an attachment to the seat part structure.
  • the bracket is preferably mounted on the seat part structure to save space, the exact position depending on the requirements. For simple storage, a simple pivoting movement, a small space requirement and a low weight with maximum stability, the bracket encloses an at least approximately rectangular base area and can be pivoted about a longitudinal side.
  • the movable anti-submarine ramp in particular in the form of a pivotable bracket, is preferably pretensioned, generally by at least one spring, so that pyrotechnic triggering can be avoided.
  • the spring is set so that it can also set up the bracket when the vehicle seat is in use.
  • a pivotable pawl, a hook or another holding element preferably holds the anti-submarine ramp (the bracket) in the normal case, it being possible for this to be non-positive and / or positive.
  • the pivoting movement of the bracket is preferably triggered electrically, so that the sensors in the vehicle, for example for the airbag, can be used.
  • the system becomes pre-safe, ie the anti-submarine ramp can be activated before the actual crash, for example in a phase of severe braking.
  • the holding element is released by an actuator, for example by a servomotor or a magnet, which normally holds the holding element at least indirectly and releases it at the latest when the crash occurs, for example by a change in its magnetic field due to a change in its current supply.
  • All of the holding elements, actuators and the like are preferably arranged within the construction space enclosed by the flat bracket and build up only a little, so that the construction space requirement is small and the influence on the seating comfort is negligible.
  • the bracket In order to support the erected position (active position) of the bracket, the bracket preferably has at least one support which, for example, folds out, so that a return movement is prevented.
  • FIG. 1 is a partially schematic section through a vehicle seat designed according to the invention
  • Fig. 2 is a plan view of the active anti-submarine ramp
  • a vehicle seat 1 for a motor vehicle has a seat part 3 with a seat part structure 5 designed as a shell and a seat cushion 7.
  • a wedge-shaped recess 9, which widens towards the front in the direction of travel, is formed within the seat cushion 7 and normally ensures the seat cushion 7 rising forwardly in the direction of travel.
  • an active anti-submarine ramp 11 is provided which quickly stiffens the seat cushion 7, so that an immersion movement of the occupant is stopped or prevented.
  • two aligned first bearings 13 are provided on the seat part structure 5 in the region of the front edge thereof, which support a bracket 15 which almost completely encloses a rectangular base surface such that it can be pivoted about a longitudinal side.
  • Two first springs 17 each arranged next to one of the first bearings 13 bias the tubular profiled bracket 15 upwards.
  • a stop 19 is fixedly attached, which is initially arranged at a distance from the seat part structure 5.
  • a pawl 25 is provided in the middle of this longitudinal side of the bracket 15, which is pivotably mounted on the seat part structure 5 by means of a second bearing 27, * its pivot axis being parallel to that of the bracket 15, and which holds the prestressed bracket 15 in a form-fitting manner ,
  • the pawl 25 is in turn held at the end facing away from the bracket 15 by a transverse pin 29 of a two-armed lever 31 which is pivotally mounted by means of a third bearing 33 about an axis parallel to the pawl 25 and the bracket 15.
  • An adhesive plate 35 attached to the lever 31 at the end facing away from the transverse pin 29 is held by a magnet 37.
  • the magnet 37 can be designed as a normal electromagnet which, when energized continuously. Adhesive plate 35 holds. In the present case, however, the magnet 37 has a permanent magnet for holding the adhesive plate 35 and a normally de-energized electromagnet which, in the event of current supply, builds up a magnetic field which compensates for or at least weakens that of the permanent magnet.
  • the adhesive plate 35 is thereby released and the lever 31 pivots about the axis defined by the third bearing 33.
  • the adhesive plate 35 is raised and the cross pin 29 is lowered.
  • the pawl 25 in turn now pivots the transverse pin 29, releasing the bracket 15 located in its flat position, ie the rest position described above.
  • the first springs 17 pivot the bracket 15 so that it moves away from the seat part 5 and bears against the front of the two upper sides of the recess 9.
  • the supports 21 fold downward by the pretensioning of the second springs 23 until they are not shown in more detail. made stops of the bracket 15, the seat structure 5 or the seat cushion 7 are stopped and with their end faces on the seat structure 5. This prevents the bracket 15 from moving downward due to vertical forces introduced by the occupant.
