[0004] Child safety device for mounting on a vehicle seat

[0005] Description

[0006] The invention relates to a child safety device for mounting on a vehicle seat, comprising at least one first locking mechanism and at least one second locking mechanism.

[0007] Child car seats designed for installation on a vehicle seat are well-known in the art. These seats have been available for some time. Such child car seats serve as seating for children, babies, and toddlers, offering them increased protection, particularly in the event of an accident and / or emergency braking. These child car seats can be secured using the car's seat belt system or via Isofix anchors. This type of installation secures the child car seat to the vehicle seat in the event of an accident, ensuring that it remains in place and is not thrown forward, especially in a rear-end collision and / or emergency braking.

[0008] The safety of children in road traffic or in accidents must be further improved.

[0009] Furthermore, child car seats are often transferred between different vehicles and / or installed and removed. It is therefore particularly important that the child car seat's attachment to the vehicle seat is as stable as possible. At the same time, it is also desirable for the attachment to allow for some adjustability in order to optimally adapt the child car seat to different vehicle seats, especially their angles. MEISSNER BOLTE M / CUU-405-PC

[0011] EP 0619201 Al shows a child safety seat with two releasable coupling devices. When the first coupling device is engaged, the second coupling device is positioned to hold the seat body rigidly against the support structure of the coupling device. This allows the child seat to be rigidly attached to the vehicle. However, this system is considered to have room for improvement in terms of its flexibility and / or stability.

[0012] The object of the present invention is to provide a child safety device for mounting on a vehicle seat which meets the above-described requirements regarding stability, safety and universal applicability in the most cost-effective and least prone to failure possible manner.

[0013] This problem is solved in particular by the features of claim 1.

[0014] The problem is solved in particular by a child safety device for installation in a vehicle, comprising a child seat and / or a child seat base having a main body, as well as at least one first locking mechanism, preferably two first locking mechanisms, and at least one second locking mechanism connected to the main body via a connecting device, each for releasably locking the child safety device to the vehicle, wherein the at least one first locking mechanism and the at least one second locking mechanism are arranged at opposite ends of the child safety device, wherein the length of the connecting device is adjustable and / or wherein the second locking mechanism has two coupling sections, each designed for coupling to the vehicle and separated from each other, preferably by at least 3 cm and / or at most 30 cm.are spaced apart.

[0015] One advantage of this design is that the child safety device can be installed in a vehicle relatively securely thanks to at least one primary and at least one secondary locking mechanism. In the event of an accident, the combination of the primary and secondary locking mechanisms prevents the seat from rotating around a single axis. Furthermore, the child safety device can be adjusted to the vehicle seat by adjusting the length of the connecting linkage. In particular, the inclination of the child safety device can be adjusted. MEISSNER BOLTE M / CUU-405-PC

[0016] 3

[0017] The two spaced-apart coupling sections of the second locking mechanism allow the child safety device to be held particularly securely in the area facing away from the vehicle's seatbacks. Specifically, the two coupling sections work together to counteract any tilting motion around a front-to-back axis. Because the coupling sections are relatively close together, the holding forces can effectively combine. Furthermore, the coupling sections are less obtrusive when they are positioned relatively close together.

[0018] In particular, the child safety seat can be individually adjusted to the vehicle seat, especially its inclination, which increases flexibility.

[0019] It should be noted that, within the scope of this invention, the term "child seat" is to be understood as a generic term encompassing (classic) child seats, infant carriers, booster seats, booster seats, etc. For example, the child seat of this invention could be a (classic) child seat. Generally, however, unless otherwise specified in the specific context, "child seat" is always to be understood as an abbreviation for "child seat, for example, infant carrier, booster seat, and / or booster seat." Similarly, within the scope of this invention, features intended for a (classic) child seat are also generally applicable, for example, to an infant carrier, a booster seat, and / or a booster seat, and vice versa (unless otherwise stated).

[0020] Preferred embodiments are set forth in the dependent claims.

[0021] Preferably, the at least one first locking mechanism is arranged at a first height and the at least one second locking mechanism is arranged at a second height (which differs from the first height in at least one usage configuration of the child safety device), in particular a lower height.

[0022] Preferably, the at least one first locking mechanism is rotatably mounted on the main body about a first axis and / or the at least one second locking mechanism is rotatably mounted on the connecting device, in particular about a second axis, and / or the connecting device is rotatably mounted on the main body, in particular about a third axis.

[0023] Preferably, the connecting device has an upper section, a lower section (referring to at least one usage configuration), and a locking device, wherein the lower section is displaceable relative to the upper section and the MEISSNER BOLTE M / CUU-405-PC

[0024] 4

[0025] The locking device is designed to lock the lower section relative to the upper section in at least two different length settings, in particular such that the locking mechanism acts against both a shortening and an elongation of the connecting section and / or withstands a thrust force acting when the child safety device is supported only at its end associated with the first locking device and at the second locking device and / or withstands a thrust force of at least 20 N, preferably at least 200 N, more preferably at least 400 N and / or at most 10 kN.

[0026] In one embodiment, the connecting device of the child restraint system can include a force limiter and / or be operatively connected to a force limiter. The child restraint system is preferably configured such that, in the event of a vehicle impact, the at least one first locking mechanism rotates about the first axis, thereby subjecting the force limiter to a load. The force limiter reduces peak loads in the child restraint system during a vehicle impact. In a rear-end collision, the force limiter can provide force limitation and damping. For this purpose, at least one energy-converting component can be used, which dampens the movement when the connecting device is additionally loaded, thereby reducing the restraining forces and moments for the child seated in the child restraint system.The force limiter can be used to absorb the impact forces acting on a connection device of a child safety seat as a result of a sudden, high impact load, thus protecting people or objects against impulse forces. The force limiter dampens the impulse forces in particular and simultaneously allows for (slight) give.

[0027] In another embodiment, the force limiter can be a component that deforms upon exceeding a predetermined force, preferably irreversibly, by absorbing energy. The predetermined force of the force limiter is preferably above a threshold value of the connecting device. This improves safety by preventing the force limiter from activating prematurely.

[0028] Preferably, the force limiter has a honeycomb structure, preferably made of aluminum. Alternatively or additionally, the force limiter can comprise a printed element or a two-stage printed element. Preferably, the force limiter is arranged at the lower end of the connection device. These structures can permanently deform under energy absorption when a certain force is exceeded, thus absorbing forces acting on the connection device. MEISSNER BOLTE M / CUU-405-PC

[0029] 5

[0030] Alternatively, the force limiter can comprise a spring element, preferably at least one hydraulic spring, which is arranged on the upper section of the connecting device, preferably as the upper section of the connecting device, or is arranged on both the lower and upper sections of the connecting device. For example, a hydraulic spring can be arranged laterally or behind the connecting device.

[0031] In a further embodiment, the at least one second locking mechanism can be arranged on the lower section of the connecting device, and / or the locking device can be arranged at the lower end of the upper section of the connecting device. The locking device can be arranged between the upper and lower sections. Preferably, the upper section terminates in the locking device. The lower section of the connecting device is preferably movably arranged within the locking device. The upper and lower sections of the connecting device can be slidably connected to each other.

[0032] Preferably, the upper and lower sections (viewed from the side) of the connecting device overlap, in particular such that the upper section encloses the lower section in an overlap area or vice versa. The upper and / or lower section(s) may be designed as a tube or profile (e.g., C-profile) or comprise such a component.

[0033] Preferably, the locking device comprises an engagement element that can be moved from a locked position, preferably by means of an actuating element, to an unlocked position. Preferably, a spring holds the engagement element in the locked position. Preferably, the engagement element is designed as a rod and / or pin. Preferably, the actuating element is designed as a push button, rotary knob, lever, and / or slider. The engagement element can be moved to the right or left and / or forward or backward. The engagement element can engage in the connecting device, preferably in a blind hole, through hole, and / or notch / groove of the connecting device. The engagement element can lock the upper and lower sections of the connecting device relative to each other to prevent the described sections from shifting against each other.In the unlocked position of the engagement element, the upper section can slide relative to the lower section of the connecting device. Once the engagement element has been moved to the unlocked position, the length of the connecting device can be adjusted. MEISSNER BOLTE M / CUU-405-PC.

[0034] 6

[0035] In a further embodiment, the locking device can comprise a transfer element which transmits the movement of the actuating element to the engagement element, wherein preferably the engagement element and the actuating element are formed in one piece, or wherein the engagement element and the transfer element are formed in one piece, or wherein the transfer element and the actuating element are formed in one piece, or wherein the engagement element, the actuating element and the transfer element are formed in one piece, preferably as a rocker.

[0036] In a further embodiment, the at least one first locking mechanism and the at least one second locking mechanism can comprise an Isofix anchoring device. In a preferred embodiment, the child safety device comprises two second locking devices (coupling devices) which can be arranged on the lower section of the connecting element. The two second locking devices can (considered together) be fork-shaped. The first and second locking devices can point in the same direction and can be oriented horizontally (with respect to a usage configuration of the child restraint device).

[0037] The Isofix anchorage devices can have so-called locking arms with fasteners that engage with Isofix brackets in the vehicle seat. Two Isofix brackets can be arranged in a line behind the point where the seat cushion transitions into the backrest of the vehicle seat on which the child seat is to be installed. The first two locking mechanisms of the child restraint system can engage with these Isofix brackets. The Isofix brackets can be designed as horizontal, rigid bars. This allows the child restraint system to rotate around its first axis when the first two locking mechanisms are secured to the Isofix brackets.

[0038] Furthermore, one or two additional Isofix anchor points may be located in the lower part of the vehicle seat. At least one second locking mechanism may engage in these one or two Isofix anchor points. The Isofix anchor points' locking mechanisms may be movable between a closed position (locked state) and an open position (unlocked state). The locking mechanisms may be pre-tensioned in the open position.

[0039] In general, the at least one first and at least one second locking mechanism can be identical. MEISSNER BOLTE M / CUU-405-PC

[0040] 7

[0041] The at least one second locking mechanism can be located at the lower end of the lower section of the connecting device. The at least one second locking mechanism can be moved from a working position to a rest position (by rotating the connecting device around its second axis) and can be locked in the working and / or rest position by means of a fastening element. In the working position, the at least one second locking mechanism can be at a 90° angle (horizontally aligned with respect to a usage configuration of the child restraint device) to the connecting device. In the rest position, the at least one second locking mechanism can be aligned with the connecting device.

[0042] In another embodiment, the child safety device can comprise a lower surface for resting on the seat surface of a vehicle seat and a rear surface for support against the backrest of the vehicle seat.

[0043] Preferably, the connecting device can be a telescope and / or a rail, or comprise the like, and its upper section can be connected to the child seat or child seat base. The connecting device can be attached to the front end of the child seat or child seat base, which points forward when the child seat or child seat base is installed.

[0044] In a further embodiment, the upper section of the connecting device can be pivotally connected to the main body, and the connecting device can be folded up under the child seat base or under the child seat itself. Additionally or alternatively, the lower surface of the main body (of the child seat or the child seat base) can include a recess into which the connecting device can be folded, creating a flat lower surface.This allows the child safety device to be easily transported and also to be used in vehicles that do not have an Isofix bracket for locking the at least one second locking mechanism, without the risk of the child seat damaging the vehicle seat on which the child seat is to be installed due to the presence of the at least one second locking mechanism protruding from the child seat.

[0045] Preferably, the length of the connecting device can be adjustable in such a way that different distances to counter-structures of the vehicle, into which the locking mechanisms engage, can be compensated for, or that the inclination of the child safety device can be adjusted. This allows the MEISSNER BOLTE M / CUU-405-PC

[0046] 8

[0047] Child safety devices can be installed in different vehicles, and the different inclinations of the vehicle seats can also be compensated for or adjusted.

[0048] The Isofix anchor points are fixed in the vehicle and can vary depending on the vehicle. Adjusting the length of the Isofix connector can compensate for the tilt of the vehicle seat. If the child restraint system is not positioned horizontally in the vehicle seat, the length of the connector can be adjusted, or the connector can be extended; more precisely, the lower section is extended to position the child restraint system at the correct angle. As a result of this adjustment, the child seat or child seat base may be lifted from the vehicle seat and rotated around its first axis.

[0049] This also creates a gap between the child restraint system and the vehicle seat (the child seat or base no longer rests completely on the vehicle seat with its lower surface), with the gap being largest at the front of the child restraint system and decreasing towards the first locking mechanisms. If a gap exists between the child restraint system and the vehicle seat, support is provided largely or entirely by the first and second locking mechanisms. Furthermore, the length of the connecting link can be shortened as much as possible to allow for convenient storage of the child restraint system.

[0050] In another embodiment, the child safety device can include a footrest. The footrest can be located on the connecting device or at the front end of the child seat or child seat base.

[0051] The present invention further relates to a method for installing the child safety device on a vehicle seat, comprising: a) providing the child safety device on a vehicle seat; b) attaching the two first locking mechanisms to the vehicle seat; c) adjusting the length of the connecting device such that the at least one second locking mechanism can engage in the corresponding counter-structure of the vehicle; and d) optionally further adjusting the length of the connecting device such that a certain inclination of the child seat or the child seat base is compensated for.

[0052] The features and embodiments mentioned for the child safety device can also be used in the method for installing the child safety device on a MEISSNER BOLTE M / CUU-405-PC.

[0053] 9

[0054] The vehicle seat may be implemented. In particular, functional features and / or purpose specifications may be implemented as concrete process steps.

[0055] The length of the connecting device can be adjusted using a locking mechanism. The locking mechanism preferably comprises an engagement element that can be moved from a locked position, preferably by means of an actuating element, to an unlocked position. In the unlocked position, the length of the connecting device can be adjusted. The adjusted length can then be locked by moving the engagement element into the locked position.

[0056] The present invention also relates to the use of the above child safety device for adjusting the inclination of the child seat or child seat base in relation to a usage configuration.

[0072] Figure 1 (see also Fig. 12) shows a side view of the child safety device 2 according to the invention, which can be installed in a vehicle, in a usage configuration. The child safety device 2 comprises a child seat base 4 with a lower surface 22 for resting on the seat surface of a vehicle seat and a rear surface 24 for support against the backrest of the vehicle seat. Furthermore, the child safety device 2 has two first locking mechanisms 6 (only one visible) and a second locking mechanism 8. The locking mechanisms 6 and 8 can be designed as Isofix anchorage devices and can each serve to releasably lock the child safety device 2 in the vehicle.

[0073] The two first locking mechanisms 6 are preferably arranged at a first height and define a first axis, and the second locking mechanism 8 is arranged at a second height, differing from the first.

[0076] The connecting device 10 comprises an upper section 12, a lower section 14, and a locking device 16. The connecting device 10, or rather its upper section 12, is attached to the front end 26 (which points forward when the seat or seat base is installed) of the child seat base 4. The second locking mechanism 8 is located on the lower section of the connecting device 10, and the locking device 16 is located at the lower end of the upper section of the connecting device.

[0077] Figure 2 shows the child safety device 2 of Figure 1, wherein in Figure 2 a child seat 4 is arranged on the child seat base.

[0078] Figure 3 shows a side view of a child safety device 2 according to the invention, which can be installed in a vehicle, in a usage configuration. The child safety device 2 comprises a child seat 4 with a lower surface 22 for resting on the seat surface of a vehicle seat and a rear surface 24 for support against the backrest of the vehicle seat. Furthermore, the child safety device 2 has two first locking mechanisms 6 (only one visible) and a second locking mechanism 8. The locking mechanisms 6 and 8 can be designed as Isofix anchorage devices and can each serve to releasably lock the child safety device 2 in the vehicle.

[0079] The two first locking mechanisms 6 are preferably arranged at a first height and define a first axis, and the second locking mechanism 8 is arranged at a second height, different from the first. The second locking mechanism 8 is connected to the child seat base 4 via a connecting device 10. The second connecting mechanism 8 is rotatably mounted on the connecting device about a second axis, and the connecting device is rotatably mounted on the child seat base 4 about a third axis.

[0080] The connecting device 10 preferably has an upper section 12, a lower section 14, and a locking device 16. The connecting device 10, or rather its upper section 12, is attached to the front end 26 (which points forward when the seat or seat base is installed) of the child seat base 4. The second locking mechanism 8 is located on the lower section 14 of the connecting device 10.

[0081] 12 arranged and the locking device 16 is arranged at the lower end of the upper section of the connecting device 10.

[0082] Figure 4 shows an enlarged view of the front end 26 of a child seat base 4 of the child safety device according to the invention. The child safety device has two secondary locking mechanisms 8, which are designed as Isofix anchorage devices. The two secondary locking mechanisms 8 are connected to the child seat base 4 via a connecting device 10. The connecting device 10 is arranged at the front end 26 of the child seat base 4. The two secondary connecting mechanisms 8 are rotatably mounted on the connecting device 10 about a second axis, and the connecting device 10 is rotatably mounted on the child seat base 4 about a third axis.

[0083] The connecting device 10 has an upper section 12, a lower section 14, and a locking device 16. The two secondary locking mechanisms 8 are arranged on the lower section of the connecting device 10, and the locking device 16 is arranged at the lower end of the upper section of the connecting device 10. The two secondary locking devices 8 are preferably (when considered together) fork-shaped. Figure 4 further shows a schematic representation of an engagement element 20 of the locking device 16 in various positions. The engagement element 20 can be moved from a locked position to an unlocked position. By means of the locking device 16, the length of the connecting device 10 can be locked (and thus adjusted).

[0084] Figure 5 shows an enlarged view of the front end of a child seat base of the child safety device according to the invention, as depicted in Figure 4, and additionally with a force limiter 18. The force limiter 18 is located in the lower section 14 of the connecting device 10. The two first locking mechanisms 6 of the child safety device 2 are preferably configured such that, in the event of a vehicle impact, they rotate about the first axis to apply force to the force limiter 18. The force limiter 18 preferably has a honeycomb structure and consists (at least partially, optionally at least 50 wt.% or at least 90 wt.%) of aluminum. Alternatively or additionally, as shown in Figure 5, the force limiter 18 can be a printed element (center) and / or a two-stage printed element (bottom), or comprise the corresponding elements.

[0085] Figure 6 shows an enlarged view of the front end of a child seat base 4 of the child safety device according to the invention as shown in Figure 4 with an additional force limiter 18. The force limiter 18 is (or comprises) a hydraulic spring, MEISSNER BOLTE M / CUU-405-PC

[0086] 13 which is arranged or attached to the upper section 12 and the lower section 14 of the connecting device 10 and is located behind the connecting device 10.

[0087] Figure 7 shows an enlarged view of the front end 26 of a child seat base 4 of the child safety device according to the invention as shown in Figure 4 with an additional force limiter 18. The force limiter 18 is a hydraulic spring which is designed as the upper section 12 of the connecting device 10.

[0088] Figure 8, similar to Figure 6, shows an enlarged view of the front end 26 of a child seat base 4 of the child safety device according to the invention, with a hydraulic spring as a force limiter 18. According to Figure 8, the hydraulic spring is arranged laterally next to the connecting device 10.

[0089] Figures 9A and 9B show enlarged views of the front end of a child seat base 4 of the child safety device according to the invention, as shown in Figure 4. Figures 9A and 9B show two different lengths of the connecting element 10. Figure 9A shows a shorter connecting element 10 than Figure 9B. The lower section 12 is displaceable relative to the upper section 14, so that the length of the connecting element is adjustable. The locking device 16 can lock the lower section relative to the upper section in the length settings shown in Figures 9A and 9B (at least against a shortening displacement, optionally in both directions). By adjusting the length of the connecting element, different distances from counter-structures of the vehicle into which the locking mechanisms 6, 8 engage can be compensated for and / or the inclination of the child safety device 2 can be adjusted.The connecting device 10 is preferably designed as a telescope.

[0090] Figures 10A and 10B show an enlarged view of the front end 26 of a child seat base 4 of the child safety device according to the invention, as shown in Figure 4. The connecting device 10 is folded up under the child seat base 4. As shown in Figures 10A and 10B, the connecting device 10 is pivotally mounted on the child seat base 4.

[0091] The second locking mechanisms 6 are preferably rotatably mounted about a second axis on the lower section 14 of the connecting device 10, so that the connecting device 10, together with the two second locking mechanisms, can be folded under the child seat base 4. The lower surface 22 of the child seat base 4 of Figure 10B has a recess in which the connecting device 10, together with the MEISSNER BOLTE M / CUU-405-PC

[0092] 14 second locking mechanism is folded in (partially or completely) so that preferably a flat surface of the lower surface 22 is created.

[0093] Figures 11A-11C show an embodiment of an ISOFIX anchoring device according to the present invention. The ISOFIX anchoring device comprises a sleeve 28, a shell 30, a fastening element 32, a locking element (not shown), and a connecting rod 34. The shell 30 is slidably mounted in the sleeve 28. The fastening element 32, the connecting rod 34, and the locking element are each movably connected in or to the shell 30. The fastening element 32 has a first 36 and a second 38 contact surface, which are arranged at intervals around a circumferential direction of the mounting hole 40. Furthermore, the ISOFIX anchoring device preferably includes an elastic device 44 which tends to allow the fastening element 32 to transition from an engaged state to a disengaged state.

[0094] In the unlocked state, a sliding section 42 of the connecting rod 34 rests against the first contact surface 36 to prevent the connecting rod 34 from moving to the right (see Fig. 11A).

[0095] When the anchoring device with Isofix brackets is engaged, the fastening element 32 rotates about an axis of the mounting hole 40, causing a sliding section 42 of the connecting rod 34 to disengage from the first contact surface 36 (see Fig. 11B). The connecting rod 34 then slides towards the fastening element 32 under the tensile force of an elastic device 44, causing the sliding section 42 to bear against the second contact surface 38 (see Fig. 11C). When the sliding section 42 is in contact with the second contact surface 38, the fastening element 32 is prevented from rotating about the axis of the mounting hole 40, thus locking the fastening element 32 in the engaged position.

[0096] It should be noted here that all the parts described above, considered individually and in any combination, especially the details shown in the drawings, are claimed to be essential to the invention. Modifications to this are familiar to those skilled in the art.
