Abstract
Abstract A protection device for sensor means (1) in a vehicle (2) such as a missile is described. The protection device is characterized particularly by a support (3) attached in the vehicle with a first flange means (4) and a protecting cap (7) with a second flange means (8). A flexible tightening means (9) is arranged between the limiting surfaces (10, 11) of the flange means in such a manner that a substantially gastight space is created, partly limited by the cap (7) and including the sensor means (1). At least one attaching means (13, 14) is so formed and arranged, that a compressive force on the cap, generated by overpressure in the space (12), brings the cap (7) to perform a movement relative to the sensor means (1) with a composant of movement in a direction away from the sensor means (1) and at least one composant of movement perpendicular to said direction, before being released from the vehicle. The limiting surfaces (10, 11) of the flange means are mutually so formed and arranged, that said movement is made possible.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
224 words
A protection device for sensor means (1) in a vehicle (2), preferably an air vehicle, such as a missile, characterized in that it comprises a support (3) attached in the vehicle (2) with a first flange means (4) surrounding said sensor means (1) about an axis (5) in the active direction (6) of the sensor means (1), further comprising a cap (7) protecting the sensor means (1), the cap being provided with a second flange means (8) at which a flexible tightening means (9) is so arranged, tightening between the limiting surfaces (10, 11) of said flange means (4, 8), that a substantially gastight space (12) is created, partly limited by said cap (7), including the sensor means (1), at which at least one attaching means (13, 14) is so formed and arranged, that a first compressive force on the cap (7) relative to the vehicle (2), achieved through overpressure generated by a source of gas in said space (12), brings the cap (7) to perform a movement relative to the sensor means (1) with a composant of movement in the active direction (6) and at least one composant of movement perpendicular to the active direction, before it is released from the vehicle (2), the limiting surfaces (10, 11) of the flange means (4, 8) being so formed, that said movement is made possible.
Claim 2
Dependent Claim
224 words
A protection device for sensor means (1) in a vehicle (2), preferably an air vehicle, such as a missile, characterized in that it comprises a support (3) attached in the vehicle (2) with a first flange means (4) surrounding said sensor means (1) about an axis (5) in the active direction (6) of the sensor means (1), further comprising a cap (7) protecting the sensor means (1), the cap being provided with a second flange means (8) at which a flexible tightening means (9) is so arranged, tightening between the limiting surfaces (10, 11) of said flange means (4, 8), that a substantially gastight space (12) is created, partly limited by said cap (7), including the sensor means (1), at which at least one attaching means (13, 14) is so formed and arranged, that a first compressive force on the cap (7) relative to the vehicle (2), achieved through overpressure generated by a source of gas in said space (12), brings the cap (7) to perform a movement relative to the sensor means (1) with a composant of movement in the active direction (6) and at least one composant of movement perpendicular to the active direction, before it is released from the vehicle (2), the limiting surfaces (10, 11) of the flange means (4, 8) being so formed, that said movement is made possible.
Claim 3
Dependent Claim
44 words
A protection device according to claim 1, characterized in that at least either of the limiting surfaces (10, 11) of the flange means (4, 8) for at least a portion of its circumference is generated by a line inclined relative to the axis (5).
Claim 4
Dependent Claim
39 words
A protection device according to claim 1, characterized in that at least either of the limiting surfaces (10, 11) of the flange means (4, 8) for at least a portion of its circumference is generated by a non-linear line.
Claim 5
Dependent Claim
37 words
A protection device according to any one of claims 1 to 3, characterized in that at least one limiting surface (10, 11) has the form of the inner or outer side of a frustum of a cone.
Claim 6
Dependent Claim
74 words
A protection device according to any one of claims 1 to 4, characterized in that at least two attaching means (13, 14) are preferably diametrically arranged, in the form of a first and a second shear pin in recesses in the first and the second flange means (4, 8), respectively, with their directions substantially perpendicular to said axis (5), the first shear pin showing substantially better resistibility towards shearing than the second shear pin.
Claim 7
Dependent Claim
56 words
A protection device according to any one of claims 1 to 5, characterized in that the limiting surfaces (10, 11) show such a dimension in said active direction (6), and the tightening means (9) is so arranged, that the cap is allowed a certain acceleration length relative to the vehicle (2) before being released from it.
