摘要： The invention relates to a sensor fastener arrangement (10a-f) for holding a sensor device (3). The sensor fastener arrangement (10a-f) comprises a plurality of fastener elements (20a, 20b). The fastener elements (20a, 20b) are configured to arrange the sensor device (3) to a platform (1). Respective fastener element (20a, 20b) is rigid in a first state and reversibly deformable in a second state. When the platform (1) of the sensor device (10a-f), and/or the sensor device (3), is exposed to an impact force, in turn exposing a fastener element (20a, 20b) to a compressive force exceeding a critical load of that fastener element (20a, 20b), the fastener element (20a, 20b) goes from being in the first state to temporarily being in the second state. Thereby the fastener element (20a, 20b) goes from having a first rigid shape to temporarily being reversibly deformed, after which, when the impact force is terminated, the fastener element (20a, 20b) goes from temporarily being in the second state back to being in the first state. Thereby the fastener element (20a, 20b) goes from temporarily being reversibly deformed to having the first rigid shape.
