Declarations under Rule 4.17: as to the identity of the inventor (Rule 4.170) as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(ii)) as to the applicant's entitlement to claim the priority of the earlier application (Rule 4.17(iii)) of inventorship (Rule 4.17(iv)) = (54) Title: SAFE-WALKER W O 20 19/0 2267 6 Al (57) : The present invention describes a safe-walker, which is functionally a combi- nation of a wheel-chair (WC) and a walker, with fall prevention support frame (SF) integral with a seat movement (SM) mechanism to enable a user, at least, to walk or to stand upright. The seat movement (SM) mechanism includes a pair of substantially L-shaped roller tracks (RT) with grooves within which rollers carrying seat slats (WP) move back or forth to take up either (i) seat in place (AB), or (ii) seat moved-away (BD) to give space and to allow the user to walk within that space. The seat movement (SM) is automatically operated by a link- age (EF) when the person stands up or sits down. The safe-walker is fail-safe because if the automated seat movement (SM) does not work, the user is still supported by a chest harness (CH) connected to the support frame (SF). The safe-walker is foldable.
