Definitions

  • the present invention concerns a quick-release device for safety belts.
  • Safety belts commonly used in motor vehicles generally include elements that support them to the vehicle's chassis, a retaining strap connected to the support, a locking buckle to allow a user (for example a driver or passenger) to put on the belt, and regulating devices to adapt the belt to the user's physiognomy.
  • the belt has the form of a textile strap or, more generally, is made of a flexible, non-stretchable material.
  • safety belts keep the user against the seat, avoiding impact against the dashboard or windshield.
  • the buckle difficult, or the buckle also could be damaged by the impact or simply be in a non-accessible position, blocking the user in the seat and hampering emergency operations.
  • the user could find himself in extremely high-risk conditions in case of a fire on board or if the motor vehicle falls into a stretch of water.
  • the safety belts include various straps, each supplied with its own locking device to link to a central buckle in order to fasten the safety belts.
  • the purpose for the invention herewith is therefore to provide a quick-release device for safety belts adaptable to any type of safety belts: above all else, those commonly used in motor vehicles on public roads.
  • a further scope of the present invention is to provide a quick-release device for safety belts that allows the activation also in an automatic way.
  • scopes of the present invention are to provide a quick-release device that is easy to use, reliable, economical, and with little encumbrance of space.
  • the present invention provides a rapid-release device for safety belts according to claim 1.
  • the device according to the invention herewith includes: a box
  • the quick-release device can be adapted to any type of safety belt thanks to the use of the movable blade and to the presence of the fixing plate.
  • the blade is effective on any kind of belt and, by means of the fixing plate, it is possible to locate the device on any segment of the belt itself, e.g. on
  • the device has a simple structure, with low production costs, and can be actuated in an automatic way, as will be described better subsequently.
  • - Fig. 1 illustrates an assonometric view with parts that have been removed for sake of clarity of a first embodiment of the quick-release device for safety belts according to this invention
  • - Fig. 2 illustrates a longitudinal section along line II-II of figure 1 of a modified embodiment of the present invention
  • Fig. 3 illustrates a transversal section of the quick-release device along to line III- ⁇ i of figure 2;
  • FIG. 4 illustrates a longitudinal section of a further embodiment of the present invention similar with that of figure 2;
  • FIG. 5 illustrates the schematic assembly of the quick-release device of figure 1 assembled on a common safety belt.
  • the quick-release device 1 comprises an elongated box shaped housing 2 having a lower base 3 and a longitudinal groove 10 carried on lower base 3, a cutting device 4 that slides longitudinally sliding along groove 10, and actuating means 5 for cutting device 4.
  • device 1 comprises a fixing plate 6, connected to housing 2 by means of a snap fastening
  • Housing 2 has, in this non-restrictive example, a prismatic shape having an isosceles trapezoidal transversal section (it could also have a tubular curvilinear form with curvilinear or semi-curvilinear section) and comprises a couple of longitudinal lateral walls 9, lower base 3 having groove 10 and an opening 11, a transversal first end wall 12 and a second end wall 13 opposite to first end wall.
  • opening 11 is arranged near end wall 13 and is designed to allow the insertion of cutting device 4 and actuating means 5 into housing 2, while groove 10, transversal compared to portion 8 of belt 8a, is arranged along a vertical plane of symmetry S of housing 2 and extends along the entire length of portion 8 of belt 8a from end wall 12 up to opening 11.
  • the lateral walls 9 have first slits 14 arranged vertically near end wall 12 and second slits 15 arranged vertically on the junction of groove 10 and opening 11.
  • cutting device 4 comprises an inertial mass 16 of prismatic shape having a conjugated profile with that of housing 2, and a blade 17 rigidly connected to inertial mass 16 to allow its insertion into groove 10.
  • Inertial mass 16 stands on an internal surface 18 of lower base 3 and is guided laterally, when activated by actuating means 5, by second internal surfaces 19 of lateral walls 9.
  • Actuating means 5 are directly connected to inertial mass 16 and comprise a helical spring 20 placed between the inertial mass 16 itself and end wall 13 corresponding to opening 11.
  • Resilient means 30 comprises, according to a non-restrictive embodiment, elastic appendices 31 coming out of slits 15 and bent towards walls 9.
  • First position corresponds to a configuration in which portion 8 of belt 8a is undamaged and inertial mass 16, pushed removable abutment 21 of spring 20 compressed against end wall 13, has blade 17 facing a lateral border of portion 8 belt 8a.
  • second position corresponds to a configuration in which the inertial mass 16 is against stop 22, spring 20 is expanded and portion 8 of belt 8a has been cut - as will be subsequently better described.
  • spring 20 is compressed for a period that may be quite long because it extends only to the moment when its action is needed, for example after an accident.
  • spring 20 has a variable winding angle of its own spires so that, in the first position previously defined, at least three spires are not packed, that is they are not in contact with one another as shown in figure 1.
  • fixing plate 6 comprises vertical guiding protrusions 23 of portion 8 of belt 8a perpendicularly aligned to groove 10 in proximity to end wall 12 as well as in proximity of the point of conjunction of groove 10 with opening 11.
  • Fixing plate 6 also presents a security groove 29 aligned with the groove 10 and only partially engaging blade 17 to protect the user and, at the same time, to define a second guide for blade 17 itself together with the one defined by groove 10.
  • quick-release device 1 The functioning of quick-release device 1 is as follows:
  • cutting device 4 is in the initial position and housing 1 is held by means of fixing plate 6 on belt 8a of the safety belt (figure 5) in an easily accessible position, for example in correspondence with the user's shoulder or at the point of contact with the chassis.
  • spring 20 no longer has obstacles and pushes the inertial mass
  • FIG. 2 illustrates a longitudinal section of a quick-release device 50 in which actuating means 5 includes a pyrotechnic device 51 joined to second end wall 13 and connected to inertial mass 16.
  • actuating means 5 includes a pyrotechnic device 51 joined to second end wall 13 and connected to inertial mass 16.
  • the first position is defined by removable abutment 21 which, once removed, lights a match (not illustrated) to activate pyrotechnic device 51, which furnishes the cutting device 4 with the necessary power to cut portion 8 of belt 8a.
  • device 50 may comprise an inertial automatic command system 70, for example provided with accelerometer sensors to control pyrotechnic device 51.
  • the system can provide the delayed ignition of the pyrotechnic device 51 through a match whose duration is calculated to consent an adequate interval of time between the moment of the accident, during which the safety belt needs to retain the user, and the activation of the pyrotechnic device 51 itself.
  • Figure 4 illustrates a further embodiment in which actuating means 5 of a quick-release device 60 comprises a rod 61 and a holding ring 62.
  • Rod 61 located parallel to groove 10, comprises a first end portion 63 connected the inertial mass 16 and a second end portion 64 coming out from first end wall 12 and connected to holding ring 62.
  • removable abutment 21 is not provided for defining the first position.
  • fixing plate 6 includes a stop insert 66 for blade 17, disposed transversally on the inside of security groove 29 in proximity of an end of the security groove 29 facing wall 13.
  • Stop insert 66 is integral with fixing plate 6 and, defining an abutment, prevents blade 17 to accidentally lacerate the lateral edge of portion 8 belt 8 a.
  • the user actuates blade 17 by means of holding ring 62 which, after having lacerated Stop insert 66, cuts portion 8 of belt 8a. Therefore, in this case, the power for cutting is supplied by the user that acts directly on rod 61 by means of ring 62.
  • actuating means 5 of cutting device 4 can be actuated by means of compressed gas.
