Abstract: A time monitoring device, comprising an elongated strip member which is suspended between posts of a wheelchair that support the wheelchair backrest and includes a graduated time scale printed thereon; a pointer member for indicating a particular time printed on the time scale of the strip member, and which slidably engages with the strip member; a handle member which is connected to the pointer member for manually positioning the pointer member relative to the time scale of the strip member; and a securing mechanism, connected to the pointer member, for substantially preventing the pointer member from moving along the time scale of the strip member while a person is seated in the wheelchair. The time indicated by the pointer member corresponds to the time at which the person was seated in the wheelchair.
