Abstract: An airbag module to protect the automobile occupant, which includes an inflatable bag (11) from the gas that is produced by a generator when a dangerous situation to the occupant is detected, which includes a number of internal straps (15, 17 and 19) with different lengths and with each having a predetermined resistance to traction, which are joined at their ends to two areas (21 and 23) of the bag (11), limiting its deployment in the direction of the occupant. The length and resistance to traction of these straps are calibrated so that they break in succession during the deployment of the bag (11) until it reaches the occupant.

Abstract: The present invention relates to an airbag cover (11) for automotive vehicles comprising means to predetermine its breaking during deployment of the airbag cushion, incorporating an emblem (13) formed by at least two independent parts (21, 23) and which is fixed to the cover (11) by means of the aid of one or more rods arranged on its inner face and comprising at least two areas (31, 35), each of which includes snap-fitting means cooperating with the rods of each of said at least two parts (21, 23) and an intermediate area (33) between them which is configured such that it can work as a bending area of the snap-fitting plate (17) during deployment of the airbag cushion, allowing relative movement between the parts (21,23) of the emblem (13).

Abstract: Airbag module to protect a vehicle occupant in the event of a collision comprising an expandable bag (11) with gas provided by a generator with, at least, one ventilation orifice (13) sealed with a patch that comprises an elastic membrane (25) destined to be broken as a result of pressure inside the bag (11) to allow gas discharge through the ventilation orifice (13), which is covered with a cover (21) secured to the bag (11) with, at least, one tearable seam (31); hence the opening of the ventilation orifice (13) occurs when the pressure inside the bag (11) is greater than the pressure required to break the membrane (25) plus the additional pressure necessary to tear the seam (31). The invention also comprises a procedure to manufacture the bag.

Abstract: The invention relates to a non-destructive method for measuring the elasticity of templates of materials for lining automotive vehicle components, characterized in that it comprises the following steps: applying a tensile pre-load with a predetermined value P1 in a longitudinal direction to a template section (41); applying a tensile load with a predetermined value P2 in a longitudinal direction to said section (41) and measuring the longitudinal deformation produced; removing the load applied to said section (41) and measuring the residual longitudinal deformation produced. The invention also comprises an apparatus (11) for carrying out the method which comprises two fixing elements (15, 17) for fixing the section (41), one of which elements is a fixed element (15) and the other is a moving element (17), a device for applying a tensile load to the moving element (17) connected to a dynamometer (29), and a rule (31) for measuring the longitudinal deformation of said section (41).

Abstract: The present invention relates to a side airbag module intended for holding back, in the event of an impact, the occupant (13) of the seat (15) of an automotive vehicle with a reclining backrest (19) by means of suitable means including an adjustment knob (31), comprising a cushion (11) configured for being vertically deployed between the protection area required for the occupant (13) and the body of the vehicle when inflated with the gas provided by a gas generator and a distance piece (21) joined at one of its ends (23) to the cushion (11) and at the other end (25) to the reclining means of the backrest (19) such that its length is reduced when the inclination of the backrest (19) is increased so that the deployed cushion (11) can be properly positioned no matter what the required inclination of the backrest (19) of the seat (15) may be.
