Abstract

Seatbelt Panic Release Mechanism installed inside or outside the standard seatbelt retention mechanism where in case of an accident the S.P.R.M. is activated and turns on a light (N6) that exists on the top of the seatbelt retention mechanism (N5) wherby the occupant of the seat may then press a button (A1) fitted on the top of the seatbelt retention mechanism in order to activate a detonator (F1) that unblocks the seatbelt retention mechanism and releases the seatbelt.

Description

DESCRIPTION

SEATBELT PANIC RELEASE MECHANISM

(S.P.R.M.) The present invention concerns safety seatbelts - restraint

mechanisms attached on all types of vehicles, private and passenger cars, as well as trucks and buses.

Until now in the case where the unlocking of the restraint mechanism does not function, either due to the mechanical seizure or for any other reason, the user cannot release the mechanism as there is not a safety system. The advantage of this invention is that in the case where the apparatus that restrains the safety belt does not function as in the case of an accident the passenger can unblock the belt- restraining mechanism with the push of a button and exit from the vehicle.

The mechanism is illustrated on the diagrams and is described as follows:

To construct and install the invention we take the following steps: Step (1)

We take the mechanism for securing and releasing the safety belts, we remove the external wrappings, the plastic lever of release {diagram (b) point (3) and any other mechanical part so as to reach the state of diagram (d). We then construct the points (1-2) of diagram D measuring at right angles and at half the width of point(4) from the top 2mm for point (1) and 12mm for the construction of point (2). The holes with internal spiral and with diameter from 1-1 ,5mm.

Step (2)

We take the release lever diagram (e) to construct the point (1). This is done as follows: between points (a) and (c) we measure the middle distance arid we make notches of 3mm depth with direction from outside to inside and until point (c)

Step (3)

We construct a mechanical returnable piston as diagram (f) that has the following particulars: the piston is cylindrical in shape with a diameter of 8mm. length, i.e. the distance between points (8) and (9) approx. 25mm internal diameter point (4) approx. 4mm. pivot point (3) with a distance from point (8) approx. 8,5mm and diameter 1mm,

Step (4)

The construction of the piston diagram (h) which is thrust during the detonation has the following properties: the trunk point (1) has a hexagonal shape with a diameter of 4mm and length from point (3) till (4) 13mm. the area of percussion point (5) has a length of 14mm, breadth 5mm and thickness 1mm and is placed on the trunk from point (4) towards point (2) at an angle of 16 degrees and the centre of its distance to be aligned with the centre of the axis of the piston.

Step ( 4)

We manufacture the support base, diagram (H), of the piston, diagram (F), at the metallic frame/skeleton, diagram ( D ) as follows : we take two pieces of metal of 0,5 mm and give them the form "ω" with one foot being up and the other down so that when placed the one inside the other to have a height of 20mm, length 26mm, width Point (6) 3,5 mm and Courbet 8mm , which we set an angle in relation to the horizontal level 16 ± 3 degrees. On the upper side of "ω", point ( 3 ) we open a hole of 0,5 mm. We open diameter holes 1 - 1 ,5 mm in points (4) and (5 ) that we have marked in the middle of the distance from the edge of the horizontal length of the metals to the starting point of the bend and in the middle of their width. Holes are made in ( 1 ) & ( 2 ) at the vertical lengths of the metals that we mark based on the distances between the points (1) & (2) of diagram (D). Step (5)

We manufacture the device of diagram ( I ) as follows : we take a round solid metal diameter 1,5 mm and we give it the form "ττ" with dimensions 46mm to each end and 30mm the horizontal. We stick at each end a cylindrical metal, point ( a) , of an external diameter of 5.5 mm, an internal of 3,1 mm and width of 2mm. Along the two ends we measure 8 mm from the contact point with the cylindrical metals and close the distance, point ( b), on 28mm while the remaining distance, point (c) remains at 30mm.

Step ( 6)

Once we have completed the construction based on the steps above we do the following

We take the activated electric detonator, diagram (F) and place it between the two metals of the diagram (H) with point (3) in one of them buckled in point (3) of the other. We put and tighten two screws with a nut on the points (4) & (5) of diagram (H). We pass the support base diagram (H) and adapt and screw with four screws in (1) & ( 2) to the metal frame/skeleton diagram (D). We then take the diagram's components ( I ) and place the ring on the edges of axis diagram (C) point (2). We connect point (1) diagram (F) with point (1) diagram (A) and the suggestion of the diagram (N).

Claims

1. Seatbelt restraint mechanism which consists of a detonator attached with the sensors of the vehicle's airbag through cable. Between the cable and the detonator interpose a button with a power indicator light, that as soon as it is apprised by the sensors of the vehicle's airbag, activates the detonator. Between the detonator and the seatbelt retention mechanism a piston is inserted.
