  • the head restraint subassembly which is arranged on the back support in a displaceable manner in the backrest longitudinal direction, is used not only to support a child's head but additionally also has lateral shoulder protection cheeks which, in particular in the case of a lateral crash, are intended to ensure that a child's upper body, namely the shoulders and possibly upper arms, are supported laterally.
  • both the height of the head restraint i.e. the position of the head restraint subassembly with respect to the back support in the backrest longitudinal direction
  • the width of the head restraint namely the distance between the two lateral shoulder protection cheeks (side cheek distance) transversely with respect to the backrest longitudinal direction
  • the mechanisms for setting the position of the head restraint subassembly in the backrest longitudinal direction, on the one hand, and for setting the distance between the two lateral shoulder protection cheeks, on the other hand, are used for this.
  • the child protection system comprises: a backrest which extends along a backrest longitudinal direction; a back support of the backrest, the back support being arranged on a seat shell and configured to provide rear support of a child's torso; a head restraint subassembly of the backrest, the head restraint subassembly being movably mounted in the backrest longitudinal direction on the back support and is configured to provide rear and/or lateral support of a child's head; a first setting mechanism for setting a position of the head restraint subassembly with respect to the back support in the backrest longitudinal direction; two lateral shoulder protection cheeks which are arranged spaced apart from each other transversely with respect to the backrest longitudinal direction on a respective lateral supporting section of the head restraint subassembly; a second setting mechanism for setting a distance between the two lateral shoulder protection cheeks transversely with respect to the back
  • FIG. 1 shows a child protection system with a height-adjustable head restraint subassembly and lateral shoulder protection cheeks which can be adjusted in their distance from each other.
  • FIG. 2 shows a child protection system according to FIG. 1 with a different setting of the height of the head restraint and of the distance between the two lateral shoulder protection cheeks.
  • FIG. 3 shows a concrete design of the child protection system shown schematically in FIGS. 1 and 2 .
  • FIG. 4 shows an exploded illustration of the child protection system from FIG. 3 .
  • Embodiments are therefore based on providing a child protection system which can have convenient and reliable operability.
  • the child protection system comprises a coupling mechanism by which the two setting mechanisms of the child protection system are coupled to each other in such a manner that, when one setting mechanism for setting the associated actuating variable (height of the head restraint or distance between the side cheeks) is actuated, the other setting mechanism is also triggered.
  • the coupling mechanism provided according to embodiments is designed in particular in such a manner that, when the first setting mechanism (for setting the height of the head restraint) is actuated, the second setting mechanism (for setting the distance between the side cheeks) is triggered.
  • the coupling mechanism has a gear for converting a movement along a first direction into a movement with a component perpendicular to that first direction, i.e., for example, a gear for converting a movement in the backrest longitudinal direction (during the setting of the height of the head restraint) into a movement with a component perpendicular to the backrest longitudinal direction (for setting the distance between the two shoulder protection cheeks) or vice versa.
  • a gear for converting a movement in the backrest longitudinal direction (during the setting of the height of the head restraint) into a movement with a component perpendicular to the backrest longitudinal direction (for setting the distance between the two shoulder protection cheeks) or vice versa.
  • toothed gears, spindle gears, lever gears, traction gears, slotted guides or sliding guides or sliding wedges interacting with one another are suitable for this.
  • the gear is used for converting a longitudinal movement into a rotational movement or vice versa, for example by a rack and an associated pinion meshing therewith, by a screw (spindle) and a nut (spindle nut) mounted thereon, by a flexible traction mechanism (cable) and an associated pulley rotatable by the traction mechanism, or by a crank gear.
  • the gear is used for converting a longitudinal movement along a first direction into a longitudinal movement along a second direction, for example by a lever gear, by a guide element (for example in the form of a guide pin) guided in an associated guide track (for example in the form of a guide slot), or by interacting sliding wedges.
  • a guide element for example in the form of a guide pin
  • an associated guide track for example in the form of a guide slot
  • the distance between the two shoulder protection cheeks, which are spaced apart from each other transversely with respect to the backrest longitudinal direction, of the child protection system, that is to say the width of the backrest, can preferably be set by pivoting the supports (about a defined pivot axis).
  • an actuating element in the form of an actuating lever which is arranged in an associated recessed grip.
  • a locking mechanism is provided in order to lock a currently set height of the head restraint and a currently set distance between the side cheeks.
  • a latching mechanism which is prestreseed elastically (by a spring mechanism) in the direction of the locked state and which can be released by an associated operating element, is suitable for this.
  • Said operating element is preferably formed by the actuating element which is used for resetting the height of the head restraint and the distance between the side cheeks.
  • the actuating element is mounted movably, i.e., for example, in the form of a pivotably mounted actuating lever, such that by action on the actuating element, i.e., for example, by pivoting an actuating lever, first of all the locking mechanism can be released and then, by further action on the actuating element, for example by pulling with force applied in the backrest longitudinal direction, the one setting mechanism, i.e., in the present case, the setting mechanism for setting the length of the backrest, is actuated.
  • the other setting mechanism is also triggered at the same time by this, i.e., in the present case, the distance between the two lateral supports of the backrest is adjusted.
  • a display device for displaying the setting of at least one of the setting mechanisms is advantageously provided, which display device can be formed by a scale and an associated pointer which are each provided on one of two parts of the child protection system that can be adjusted with respect to each other, for example each on one of two backrest parts which are telescopic with respect to each other (back support, on the one hand, and head restraint subassembly, on the other hand).
  • the pointer may be designed as a display window in the form of a viewing window behind which one part of the scale can be seen.
  • At least one belt guide used for guiding a seat belt is arranged on the head restraint subassembly of the child protection system in such a manner that the position thereof is adjusted in a corresponding manner at the same time as the height of the head restraint and the distance between the side cheeks are reset.
  • the position of the belt guide of the child protection system is in each case adapted automatically to the current setting of the height of the head restraint and the distance between the side cheeks.
  • the arrangement of a respective belt guide on each of the two lateral sections of the backrest is particularly preferred here according to an embodiment.
  • FIG. 1 schematically illustrates a child protection system in the form of a child seat which has a seat shell 1 with a trough 10 and a backrest 2 protruding upward therefrom.
  • the seat shell 1 with the seat trough 10 forms a receptacle for the thighs, bottom and pelvis of a child
  • the backrest 2 is used, firstly, to support a child's back by a back support 21 and, secondly, to support a child's head by a head restraint subassembly 22 , with lateral shoulder protection cheeks 26 , 27 (side cheeks) also protruding from the head restraint subassembly 22 , which shoulder protection cheeks are used to laterally support a child in the region of the upper arms and shoulders, in particular in the event of a lateral crash, and, for this purpose, protrude spaced apart from each other transversely with respect to the backrest longitudinal direction L from a respective lateral supporting section 7 a , 7 b arranged pivotably on the head restraint subassembly 22 .
  • the backrest longitudinal direction L is understood as meaning that direction along which the spinal column of a child in a normal position in the seat shell 1 extends.
  • the head restraint subassembly 22 is also referred to below simply as head restraint although it has additional subassemblies 26 , 27 , 28 , 29 in comparison to conventional head restraints.
  • the child protection system which is illustrated in FIG. 1 , in the form of a child seat can be matched in its geometrical dimensions to the anthropometrical circumstances of a child's body in order to ensure the best possible comfort and greatest possible safety for a child using the child protection system.
  • both the height of the head restraint i.e. the position of the head restraint 22 with respect to the back support 21 in the backrest longitudinal direction L, and the distance between the lateral shoulder protection cheeks 26 , 27 (side cheeks) along a direction Q transversely with respect to the backrest longitudinal direction L can be set.
  • the backrest 2 is overall of telescopic design and comprises two backrest parts 21 , 22 which can be adjusted with respect to each other in the backrest longitudinal direction L and of which the one, lower back rest part 21 forms the back support and the other, upper back rest part 22 , which can be displaced with respect thereto in the backrest longitudinal direction L, forms the head restraint.
  • an actuating handle 3 which is arranged in a recessed grip 30 and is in the form of an actuating lever which is arranged on a head receptacle 23 (for receiving a child's head) provided on the head restraint subassembly 22 and which takes on a dual function:
  • a locking mechanism which is formed by latching elements prestressed elastically into their locked state and with which the respectively current setting of the length of the backrest is locked, can be released. This makes it possible for the first time to reset the height of the head restraint by displacing the head restraint 22 with respect to the back support 21 in the backrest longitudinal direction L.
  • the setting mechanism 20 for setting the length of the backrest L, realized by the telescopic capability of the two backrest parts 21 , 22 , is assigned a display device 4 which comprises a display or viewing window 41 provided on the first, lower backrest part, namely the back support 21 , and a scale 42 provided on the other, upper backrest part, namely on the head restraint 22 .
  • a certain excerpt of the scale 42 is visible in each case through the viewing window 41 in accordance with the relative position of the two backrest parts 21 , 22 with respect to each other in the backrest longitudinal direction L, at which cutout the current setting of the height of the head restraint can be read.
  • the scale does not absolutely have to specify the current overall length of the backrest 2 , comprising back support 21 and head restraint 22 , but rather, for easier operability, may also specify the height of a child (in cm) for which the particular setting of the length of the backrest is suitable.
  • This display device 4 leads to a further reduction in the risk of misoperations, since the operator is immediately informed about the selected setting.
  • the child protection system illustrated in FIG. 1 has a setting mechanism 25 for setting the distance between the two lateral shoulder protection cheeks 26 , 27 (side cheeks) transversely with respect to the seat longitudinal direction L.
  • the two lateral supporting sections 7 a, 7 b of the backrest 2 are mounted pivotably about an axis 24 such that, by mutual pivoting of the two lateral supporting sections 7 a, 7 b of the backrest 2 about the common bearing axis 24 , the distance between the lateral shoulder protection cheeks 26 , 27 arranged thereon is increased or reduced in a direction Q transversely with respect to the backrest longitudinal direction L, cf. FIG. 2 .
  • the two setting mechanisms 20 , 25 are coupled via a coupling mechanism in such a manner that, when the height of the head restraint increases (in the backrest longitudinal direction L), the distance between the two lateral shoulder protection cheeks 26 , 27 also increases (in a transverse direction Q transversely with respect to the backrest longitudinal direction L), cf. FIG. 2 , since a larger child generally also needs a greater amount of space transversely with respect to the backrest longitudinal direction L.
  • gear mechanisms such as, for example, a pinion gear with a rack and a pinion engaging therein, a screw or spindle gear, a traction gear with a traction mechanism and a cable pulley driven thereby, or a lever gear.
  • a coupling gear 50 which has two slotted guides 51 , 53 and 52 , 54 is used as the coupling mechanism 5 for converting a longitudinal movement of the two backrest parts 21 , 22 with respect to each other into an opposed rotational movement of the two lateral supporting sections 7 a, 7 b of the backrest 2 .
  • Said slotted guides each comprise a guide slot 51 , 52 , which runs obliquely with respect to the backrest longitudinal direction L, i.e. is inclined with respect thereto, and is in the form of an elongated hole, and a guide pin 53 or 54 , which is guided therein and is in the form of a pin or bolt.
  • the two guide slots 51 , 52 are inclined in the opposite direction with respect to the backrest longitudinal direction L, and the associated guide pins 53 , 54 each engage in a form-fitting manner in the associated guide slot 51 or 52 .
  • the two guide slots 51 , 52 running in an inclined manner are formed on an upper supporting section (extension) 210 of the lower, non-displaceable back support 21 , and the associated guide pins 53 , 54 are each provided on one of the two pivotably mounted, lateral supporting sections 7 a, 7 b of the backrest 2 .
  • the guide slots 51 , 52 are therefore formed on a subassembly (back support 21 ) which remains fixed in position during a setting of the length of the backrest in the backrest longitudinal direction L while the associated guide pins 53 , 54 are provided on a subassembly (namely on the head restraint 22 from the supporting sections 7 a, 7 b of which the lateral shoulder protection cheeks 26 , 27 protrude) which is moved during a setting of the length of the backrest in the backrest longitudinal direction L.
  • the movement of the head restraint 22 in the backrest longitudinal direction L is converted here into a movement of the two lateral supporting sections 7 a, 7 b of the head restraint 22 with a component Q transversely with respect to the backrest longitudinal direction.
  • the pivoting movements of the two lateral supporting sections 7 a, 7 b of the backrest 2 run in an opposite direction, corresponding to the opposite inclination of the two guide slots 51 , 52 , which are each assigned to one of the two lateral supporting sections 7 a and 7 b, this assignment being defined by the engagement of the two guide pins 53 , 54 , which are each provided on a lateral supporting section 7 a, 7 b, in one of the two guide slots 51 , 52 .
  • the two setting mechanisms 20 , 25 are coupled to each other via the coupling mechanism provided for this purpose in such a manner that a certain setting of the height of the head restraint or length of the backrest (in the backrest longitudinal direction L) corresponds to a setting of the width of the backrest (distance of the lateral shoulder protection cheeks 26 , 27 in the transverse direction Q), which setting corresponds to the ratio, customary for children, of height and width of shoulders.
  • a respective belt guide 28 and 29 for a seat belt is provided on the two lateral sections 7 a, 7 b of the backrest 2 , which sections are movable together with the head restraint 22 in the backrest longitudinal direction L and, in addition, can be set in their distance in a direction Q transversely with respect to the backrest longitudinal direction L.
  • a seat belt can be guided through the one or other belt guide 28 , 29 —depending in each case on the fitted position of the child protection system, for example behind the driver's seat or behind the passenger seat—in such a manner that it provides optimum protection for a child situated in the child protection system.
  • the position of the belt guides 28 , 29 is simultaneously also adjusted in a corresponding manner. This enables the position thereof always to be matched optimally to the respectively selected setting of the length of the backrest and width of the backrest, which setting in turn depends on the size of the child to be held.
  • FIGS. 3 and 4 illustrate by way of example a specific refinement and partial modification of the child protection system, only shown schematically in FIGS. 1 and 2 , in the form of a child seat.
  • the seat shell 1 of the child protection system forms a seat trough 10 for receiving the bottom and the thighs of a child and is bounded laterally by pelvis supports 16 , 17 for a child sitting in the seat trough 10 .

  • the head restraint 22 is mounted on the back support 21 of the backrest 2 in a displaceable, i.e. height-adjustable manner in the backrest longitudinal direction L, which head restraint, in the present case, involves a head restraint subassembly assembled from a plurality of components 6 , 7 a, 7 b, 8 .
  • a first constructional unit 6 of the head restraint subassembly 22 forms the actual head restraint element, which serves as a head receptacle, with a rear support 60 and two lateral supports 66 , 67 for supporting a child's head.
  • the head restraint subassembly 22 comprises, as further constructional units, two lateral supporting sections 7 a, 7 b, from the base body 70 of which there protrudes, in the region of the respective upper end, a lateral supporting cheek 76 or 77 which is used for the outer support of a respective lateral support 66 , 67 of the head restraint element 6 .
  • a lateral supporting cheek 76 or 77 which is used for the outer support of a respective lateral support 66 , 67 of the head restraint element 6 .
