Definitions

  • the invention relates to a restraint device with the features of the preambles of claims 1, 2 or 3.

  • the latter alone takes over the restraining function, the shoulder belt for adjusting the position being guided through a belt eyelet provided on the child seat.
  • this method proves to be inadequate due to excessive stress on the child's neck and chest; in addition, the belt eyelets are extremely prone to pulling out.
  • the vehicle's own seat belt is or is provided with an impact protection in the form of a component inserted or insertable flat between the child on the one hand and the seat belt on the other hand.
  • This is the abdominal and chest area of the child, if necessary, in 'about correspondingly curved or wölbbar, compared to the belts only slightly bendable and preferably padded.
  • It is connected or connectable to the lap belt and the shoulder belt with the aid of belt fastening means, in particular in a detachable manner.
  • the belt fastening means hold the pelvic and shoulder belts separately from one another at an acute angle to one another.
  • Retention devices of this type in the broadest sense are known from DE-Al-38 21 564, DE-Ul-82 09 412 and 84 36 926 and US Pat. Nos. 3, 941, 404 and 5,016,915.
  • the restraint device known from DE-Al-38 21 564 consists of two elements, namely on the one hand the impact protection referred to as a collecting body in the form of a triangular, tear-resistant plastic textile part.
  • a deflection device to be attached to the side of the respective seat in addition to the fastening points of the seat belt is provided within the vehicle. With this deflection device, the guidance of the shoulder strap is changed, namely its steepness is reduced.
  • the collecting body is matched to the deflecting device in such a way that the shoulder strap runs almost straight over the middle shoulder region of the child to the deflecting device when the three-point strap is put on.
  • This restraint device has the disadvantage that the effectiveness of the shoulder belt is worse than for adults and that fastening points for the deflection device must be selected in the vehicle which are not so good for the introduction of the belt forces in an accident how the original fastening points of the seat belt are suitable. Adjustment of the restraint device to the actual size of the child is not provided; the necessary retrofitting of the Umlenkvorrichtu ⁇ g is quite expensive.
  • DE-Ul-82 09 412 proposes a shield-shaped component made of leather for distributing the belt forces to the child, which likewise does not influence the course of the shoulder belt and therefore also has the disadvantages mentioned at the outset.
  • DE-Ul-84 36 926 proposes, in order to alleviate pressure points between the shoulder belt and the upper body of the user of three-point seat belts in vehicles, a large, pointed-bag-shaped cover with arm openings, which enables the arm to be pushed through, over the shoulder of which the shoulder belt is guided becomes.

  • This plate is connected to the seat belt of the vehicle in such a way that a single unitary part is created, namely a protective shield / belt combination.
  • the length adjustment of the straps to the individual size of the user must therefore be carried out separately on all three straps.
  • Such restraint devices can only be designated as safe for people of a very specific body size.
  • the object of the invention is to create a generic child restraint device which allows comfortable putting on and carrying with the best possible protection of the child against injuries.
  • a restraint device with the features of claim 1, 2 or 3 is proposed.
  • a restraint device according to the invention has, in addition to a comfortable and particularly safe carrying position for the child, the advantage, among other things, of being easy to put on and of enabling a particularly favorable pressure distribution of the belt on the child; in addition, the risk of neck and head injury is kept comparatively low in the event of an extreme deceleration of the driving speed. It can be used in conjunction with an additional seat cushion, although the increased seating position undesirably increases the forces on the shoulder area of the child in an accident.
  • the extension of the component below the belt fastening means is designed such that it transmits acceleration forces to the user's pelvic bones and thus even more distributed.
  • Such a downward extension of the impact protection prevents the so-called submarining, ie the user's diving through under the lap belt under strong braking acceleration.
  • the feature of claim 15 can therefore also be used advantageously independently of the realization of the characterizing features of claims 1 to 3 and also in connection with a two-point belt (pure lap belt).

Abstract

L'invention concerne un dispositif de retenue (10) pour personne de petite taille, notamment pour enfant, sur un siège de voiture, utilisable en combinaison avec une ceinture de sécurité à fixation en trois points (11, 12) pour adulte, comprenant un élément plat, notamment bombé (16) fixé, pour servir de protection antichoc, entre la ceinture et l'utilisateur, et a pour but de permettre un ajustement optimum de la sangle, tout en assurant une protection optimale évitant toute blessure de l'utilisateur en cas d'accident. Ce but est atteint grâce au fait que les moyens de fixation de la ceinture (16A, 16B; 31, 32, 36A, 36B) sont montés sur la protection antichoc (16), de manière à agir dans le sens d'un raccourcissement de l'intervalle compris entre la partie centrale de la ceinture (11) et celle se trouvant au niveau de l'épaule (12), tout en maintenant le déplacement de la ceinture normalement déterminé par la fixation en trois points de la ceinture de sécurité dans le véhicule. Un prolongement (30) de l'élément (16) au-dessous des moyens de fixation (31, 32) pour la ceinture ventrale (11) pourvu d'au moins un creux médian en bordure (28) permet de réaliser une transmission de force sur le bassin de l'utilisateur et d'empêcher 'l'effet d'enfoncement' lors d'un freinage brusque du véhicule.
