Abstract: The present disclosure relates to a locking mechanism of an armrest assembly for a wheelchair, comprising: an elongated inner arm, an elongated outer profile, and a locking handle, wherein the locking handle is configured to pivot between proximal and distal pivot positions in which the locking handle is pivoted further away from the outer profile than in the proximal pivot position. The locking handle is configured to cause the locking structure to engage with the outer profile and the inner arm to axially interlock the outer profile with the inner arm, and wherein the locking handle is configured to move the locking structure from engagement with the outer profile and the inner arm to release the outer profile from axial interlocking with the inner arm when the outer profile is in the proximal position and the locking handle is moved from the distal pivot position towards the proximal pivot position.

Abstract: The present disclosure relates to a chassis arrangement (1) for an electrically powered wheelchair (35). The chassis arrangement (1) comprises a main chassis member (3) having a first side panel (3a) defining a first side of the main chassis member (3), and a second side panel (3b) defining a second side of the main chassis member (3), the second side being opposite to the first side, wherein each of the first side panel (3a) and the second side panel (3b) has spring attachment arrangements (3g, 3h) for attachment of spring assemblies (9a, 9b, 11a, 11b), wherein each of the first side panel (3a) and the second side panel (3b) has pivot arm attachment arrangements (3e, 3f) for attachment of pivot arms (5a, 5b, 7a, 7b), wherein the main chassis member (3) has a torsional stiffness greater than 1200 Nm/degree. An electrically powered wheelchair comprising a chassis arrangement (1) is also presented herein.

Abstract: The present disclosure relates to a locking mechanism (7) of an armrest assembly for a wheelchair, comprising: an elongated inner arm (9) having a pivot end portion (9a), and a first elongated body (9b) extending from the pivot end portion (9a), an elongated outer profile (11) having a proximal outer profile end face (11a) provided with an axially extending channel (11b) configured to receive the first elongated body (9b), and a distal outer profile end portion (11c), the outer profile (11) being configured to move linearly relative to the inner arm (9), between a proximal position relative to the pivot end portion (9a) and a distal position, a locking handle (13) having a second elongated body (13a) configured to receive the outer profile (11), the locking handle (13) having a proximal locking handle end portion (13b) relative to the pivot end portion (9a) of the inner arm (9) and a distal locking handle end portion (13c), the distal locking handle end portion (13c) being configured to be pivotally attached
