Definitions

  • Child seat base for accommodating a seat element
  • the invention relates to a child seat base for accommodating a seat element of a child seat system for installation in a motor vehicle and a corresponding child seat system.
  • Child seat systems are typically used in motor vehicles to protect children from serious injury in the event of an accident.
  • a child seat system comprises the child seat itself (seat member) for accommodating a child and, in addition, a support base (child seat base) that can be installed on a vehicle seat and forms a supporting base for the child seat.
  • support bases In order to be able to use the support base with other child seats and/or to enable the child seat to be transported more easily, support bases often have mechanisms for releasably attaching child seats. However, in order to securely and easily attach the child seat to the support base, a suitable attachment mechanism is required.
  • Exemplary systems are known from EP 2 210 768 A2 and EP 1 369 295 A1.
  • Four fastening devices designed as hooks are proposed in EP 2 210 768 A2.
  • EP 1 369 295 A1 proposes fastening devices which are designed as pins.
  • the object of the invention is to propose a child seat base for accommodating a seat element of a child seat system for attachment to a motor vehicle and a corresponding child seat system, with a high level of safety in connection with the attachment of the seat element being achieved in a comparatively simple and inexpensive manner is to be achieved.
  • a child seat base for receiving a seat element (child seat) of a child seat system, the child seat base or the child seat system being configured for attachment in a motor vehicle, the child seat base having a plurality of fastening devices (fastening elements , in particular locking elements), for fastening the seat element on the child seat base, which can be brought from a locking position into a release position (and vice versa), with at least a first of the fastening devices being configured differently from at least a second of the fastening devices.
  • fastening elements fastening elements , in particular locking elements
  • the deviating configuration preferably relates to a rotatability (of the respective fastening device, whereby preferably the at least one first fastening device is rotatable and the at least one second fastening device is not, or vice versa) and/or a lockability (of the respective fastening device, preferably the locking position of the respective fastening device , in particular such that the at least one first fastening device can be locked or is locked in particular in its locking position and the at least one second of the fastening devices is not, or vice versa) and/or a shape (of the respective fastening device, in particular such that only the at least one first Fastening device includes or forms an encompassing structure, preferably a hook, but not the at least one second fastening device) and/or a choice of material (in particular such that the at least one first fastening device consists at least in sections is made of metal, in particular is made predominantly of metal, and the at least one second fastening device is made at least partially, in particular predominantly, of plastic
  • One idea of the invention lies in deliberately providing fastening devices that are configured in different ways. As a result, it can be achieved, for example, that a (possibly undetected) weak point, which could be present in a large number of at least essentially identical fastening devices, has negative effects. Furthermore, this makes it possible to design individual attachment points in a complex (or possibly also less complex) manner according to their (in particular safety-related) relevance.
  • a fastening device can be understood to mean, for example, a fastening element (possibly in one piece or designed as a coherent component).
  • the fastening element can be monolithic and/or connected to another component, e.g. B. to a connecting device.
  • a locking position is to be understood as meaning a position of the respective fastening device in which a seat element, when it is (properly) arranged on the child seat base, is held by the respective fastening device.
  • a release position is to be understood as a position in which the seat element can be detached from the child seat base (in relation to the respective fastening device).
  • the child seat system includes a child seat (seat member) for receiving children and a support base (child seat base) for providing support for the child seat, wherein the child seat can be detachably installed on the support base.
  • the child seat base can have a shell body on which the seat element can be attached.
  • the shell body can have an upper shell part and a lower shell part and/or have an at least partially hollow interior.
  • the shell body of the child seat base may have a top suitable for receiving the seat member.
  • an underside of the seat element in the front and/or, preferably, rear area can have a rod that extends from a left to a right side of the seat element, while the upper side of the shell body has one or more recess(es). ) may have to at least partially accommodate the (respective) rod when the seat element is placed on the child seat base.
  • the underside of the seat element can preferably have at least one recess running at least approximately in the transverse direction or two recesses spaced apart from one another in the transverse direction in the front and/or rear region.
  • engagement elements can be attached which, if necessary, can at least partially engage in these recesses and/or can interact with corresponding engagement elements of the seat element.
  • the child seat base can have an attachment mechanism that manages to attach the seat element to the child seat base and to detach it from the child seat base for its removal.
  • the attachment mechanism may include multiple fasteners (fasteners).
  • Two fastening devices should differ in their ability to rotate in particular if one fastening device is rotatable, in particular about a predetermined axis, and the other is not (for example only translationally displaceable and/or only deformable). However, the case can also be covered that one of the fastening devices can be rotated through a larger angle (for example an angle that is at least 1.5 times or at least 2.5 times as large) as compared to the other fastening device.
  • a (mere) difference in relation to a sense of rotation should especially not to be considered as a difference in terms of rotatability.
  • Two fastening devices should differ in terms of their ability to be locked, in particular if one fastening device can be locked and the other cannot, or if the type of locking is different (e.g. in one case via a form fit and in another case by a force fit).
  • a fastening device should be regarded as locked or correspondingly lockable if it is immovable in a locked state (or at least can only be moved so little that it is not possible to switch between the locking position and the release position).
  • Lockability in this sense should in particular not already be present if the corresponding fastening device is not accessible from the outside and therefore cannot be moved by hand, for example.
  • the fastening devices can be designed differently.
  • At least a first of the fastening devices can preferably be locked or locked in its locking position by means of at least one locking device, with at least a second of the fastening devices being movable in its locking position.
  • “mobility” does not necessarily mean that the corresponding fastening device can be moved from the outside (by hand), but (only) that it is not blocked against a (possibly even imaginary) movement of its own. In particular (as above ) only movements are considered that can generally take place when used correctly when transferring from the locking position to the release position or vice versa.
  • At least one (particularly first) - but preferably not all - fastening device(s) can comprise a hook.
  • at least one (in particular second) fastening device include a pin (but especially not a hook).
  • several or all of the first fastening devices can comprise a hook (or be designed as a hook) and several or all of the second fastening devices can comprise a pin (or be designed as a pin).
  • a variable and secure fastening system is advantageously achieved precisely through the combination of hooks (in particular in a rear area) and pins (in particular in a front area).
  • the at least one first fastening device (possibly several or all of the first fastening devices) is/are preferably (only) rotatable (ie not translationally displaceable).
  • the at least one second fastening device (or several or all second fastening devices) is (only) translationally displaceable (ie in particular not rotatable). It is also conceivable for a respective fastening device to be both rotatable and translationally displaceable (simultaneously and/or sequentially). Safety can also be improved by this variation in the basic movement.
  • the child seat base can have a support leg and/or an Isofix anchoring device.
  • the at least one first fastening device (in particular several or all fastening devices) is (are) arranged further back than the at least one second fastening device (in particular several or all of the second fastening devices).
  • a “further rear” configuration is understood to mean a configuration that is closer to a rear end of the child seat base.
  • a rear end of the child seat base is preferably defined by that end which protrudes from a seat back of the motor vehicle when the child seat base is properly positioned.
  • the respective first attachment means may be located at least 5 cm, or at least 15 cm, or at least 20 cm further back than the at least one second (or several or all second) fastening device(s).
  • the respective first fastening device can be in a rear third and/or the respective second Fastening device can be arranged in a front third of the child seat base.
  • One consideration of the present disclosure consists in particular in deliberately designing the (respective) rear attachment device to be comparatively complex and secure. It was considered that the (respective) rear fastening device is of particular importance in the event of a frontal impact and that a failure of the rear fastening device is more likely to have more serious consequences than a failure of a front fastening device. If only the front fastening device is still holding (in the event of a front crash), the seat element will have the tendency to rotate or tilt forwards due to its inertia, which is already highly problematic for the child and can also result in particularly large forces act on the (initially still holding) second fastening device, so that this also fails.
  • a comparatively complex design of the (respective) first or rear fastening device is particularly important when the child seat base is anchored or can be anchored to the motor vehicle seat via an Isofix anchorage (located at the rear) and/or another fastening structure at the rear and possibly below advantageous.
  • first fastening devices can be arranged at "the same height" (in relation to a direction from back to front).
  • second fastening devices the same applies to several or all of the second fastening devices.
  • first fastening devices and/or several or all of the second fasteners are aligned with each other in a line along a left-right direction.

Preferably, however, it is only displayed directly whether the at least one first fastening device is in its locked position or not.
  • a direct display is to be understood in particular as meaning that the display device is positively coupled to the corresponding attachment device in such a way that it is not possible to bring the attachment device into a state that deviates from a displayed state.
  • an only indirect indication means that the corresponding fastening device can be brought into a state that differs from the state displayed (possibly even if such a divergence of the displayed state from the actual state does not occur during proper use).
  • the fastening devices can be designed in different ways.
  • the fastening devices can be designed in such a way that they at least partially encompass the rod of the child seat, in particular as a hook.
  • the fastening devices can be designed as engagement elements, in particular as pins, which can at least partially engage in recesses in the child seat, for example.
