The Brava armrest is designed as equipment for mobile working devices. The product consists of three elements: operating unit, armrest and height adjustment unit. Thanks to this modularity, OEMs can configure the armrest accurately; allocation and shape of the operating elements are variable. The design is based on an ergonomic analysis of the operating sequences. Characteristic for the design is the combination of clear lines, facetted surfaces and soft forms. The colouring and the formal language emphasise the industrial character of the armrest.
