Kernrechtsfrage
Whether the AHV possession guarantee under Art. 4 HVA covers the requested electric seat lift as accessory to the wheelchair.
Extrahierter Entscheid
Yes. The lift was needed not because of a new deterioration in health, but because changed technical circumstances made the already necessary vertical mobility aid indispensable.
Extrahierte Begründung
The court held that Art. 4 HVA preserves prior entitlement in scope only if the pre-retirement need continues. Here, the insured had already required technical aids for vertical movement before retirement; the new wheelchair required a technically different solution to overcome the same longstanding height-difference problem. The request therefore remained within the possession guarantee.
