Abstract: A leg guard comprises a first, shell-like section (1) and second shell-like section (2). The first section (1) is connected to the second section (2) by means of two coaxial pivot pins (4) arranged on each side of the leg guard. A cupped part (3) is pivotally connected to the second section (2) by means of two coaxial pivot pins (5) spaced from the first pivot pins. Two coaxial guide pins (8) connected to the first section are each arranged to slide in a groove or slot in the cupped part (3). The arrangement is such that when the leg guard is bent, the second pivot pins (5) cause the cupped part (3) to move in the longitudinal direction of the leg guard, and the guide means formed by the guide pins (8) and the slot or groove guide the pivotal movement of the cupped part around the second pivot pins.
