<p>Display system designed for mounting on a helmet and comprising two image projection devices for mounting on either side of the helmet, which image projection devices each emit an image intended for an eye of the person wearing the helmet, and a visor provided with two optically transparent, reflecting optical elements, which optical elements receive the images emitted by the image projection devices and reflect them to the eye for which said image is intended, in which connection, to simplify the requirements to be imposed on the optical properties of the optical elements, the image projection devices are mounted in a plane which extends essentially horizontally through both eyes of the wearer of the helmet, and either the image projection device which emits the image reflected to the left eye is sited on the right-hand side of the helmet and the image projection device which emits the image reflected to the right eye is sited at the left-hand side of the helmet, or a flat optically transparent, reflecting element is mounted vertically between the eyes, which flat element reflects the image originating from the image projection device at the left-hand or the right-hand side, respectively, of the helmet to the optically transparent, reflecting optical element sited in front of the left or right eye, respectively. In order to be able to site the image projection devices further to the rear so that they fall completely outside the field of view of the wearer of the helmet, an optically transparent reflecting optical auxiliary element is provided which is mounted in the vicinity of the respective image projection device on or near the visor and which reflects the rays originating from the image projection device to the associated optically transparent, reflecting optical element or to the flat optically transparent, reflecting optical element, respectively.</p> |
