Kernrechtsfrage
Whether invalidity insurance must finance a second manual wheelchair for the insured.
Extrahierter Entscheid
No. The insured already had a power wheelchair for outdoor mobility and a manual wheelchair for indoor use; a second manual wheelchair was not necessary, but only a comfort-improving measure.
Extrahierte Begründung
The statutory criteria of simplicity and adequacy require a means auxiliary that is necessary and proportionate. 'Moving around' and 'establishing contacts' do not mean access to every place or every private home. Since the insured could maintain ordinary social contacts outside her home with the existing devices, additional coverage was not justified.
